Phase 3

Phase 1 was spinning for knitting.  Phase 2 was learning to spin fast and fine. Phase 3 is spinning for weaving.

The new guild season has started, and last night I had a heart to heart talk with the best weaver around, and we decided that the real problem with my weaving is that I need more twist in the warp thread.  This morning I am back to one of the old bobbins that I made for spinning very fine, along with a more precise flier whorl, all in all, resulting in easier spinning of 5,600 ypp singles at 13 or 14 tpi compared to the mere 9 tpi that I have been spinning knitting singles.  

I think the truth of the matter is that the tighter spun singles will ply up into better knitting yarns- e.g., stronger, more durable, and yes, warmer.

More work, but that is in the nature of textiles.  Sometimes better is more work.

I still have not worked out the best logistics for warping the loom at 68 epi with 2" wide sections on the warping beam ( e.g., 136 ends per section).  And, the tension box only holds 100 ends.  And, the bobbin rack only holds 72 bobbins. Still I am getting to the point where I can reasonably start thinking about these issues.

Measure!

I get teased and chided on for using the traditional spinner's measures.  In  particular, measuring grist by stating the number of "hanks" of 560 yards that can be spun from a pound of yarn.

My ordinary grist is "10s". That is 5,600 ypp yarn spun worsted. Thus, I know how many pounds of wool I have, I know how much yarn I can spin. Easy.  And, when wrapped to refusal, 10s measure ~75 wpi.  A 75 wpi single can be sleyed to produce plain weave at 68 epi/68ppi, which weighs about 1 pound/ square yard.  Likewise, 20 hanks per pound produce 2 yards of cloth per pound of wool.

Thus, using hanks, I can easily calculate how much yarn I can spin from a given batch of wool, and how much cloth I can weave from that wool.  The more weaving I do, the more useful the old English system of yarn measure is.

This also tells us that the stories we were told in grade school were just that -- stories.  The yard and the inch may have been related to some king's reach and size of hand/toe/foot, but he would have lived before the very fine weavers of Classic Greece.  They had wool, yarn, and cloth trading, so they had measures that extended from Greece to what is now Turkey and Egypt, to say nothing of the silk road with textiles moving east.

Sorry, Love; but the fine fabrics of Classical Greece were not woven on single beam, warp weighted looms.  Oh, I am sure they had such looms, but I doubt if that is what they used to weave 12 meter lengths of 68 epi (and finer) wool fabrics.  No, by Classical Greek times, it was an industry, and they were using  rather sophisticated horizontal double beam looms.  And there was trade.  With trade, there were terms to define the various aspects of textiles.  You may not name your yarns, but merchants do; now and in the past. They give them names like  "45 grams / meter, white worsted single" or white "40s".

I expect that the definitions of (or other words that indicate the same quantity): hank, yard, inch, pound, wool fineness in hanks per pound, ends per inch, pricks per inch, woolen, and worsted, were all set, and known among textile traders by the end of the Greek Classical era.   In particular, the elegance of the hanks of yarn at 560 yards tied to fineness wool and the math of  wraps per inch suggests the mathamatical acumen of Syracuse in classic times.

The fact that we have variations such as the el as a measure of length, suggests that textile measures have been around long enough for dialects to develop.  For the larger, and well nourished Greeks, 36 inches was a reasonable width for a warp. During some periods in the textile centers of  Europe, there was famine, and people were smaller, so a narrower warp allowed much easier weaving.  Thus, during periods of famine, Europeans needed a name for narrower cloth, e.g., the el.

Yards, inches, pounds, and hanks were not isolated measures, but part of an intricate system of measure, essential to a large, profitable, international industry and  systems  of trade.  In systems that goes all the way from from wool fiber to yarn to finished cloth, the old English system with grist and wool fineness in hanks per pound  is the easy way to do the math  and make sure you get correctly paid.

Wool Warp that works.

Easy! More twist!  With enough twist, you are less likely to need sizing.

So, I spin worsted 10s, @ 9 tpi, and it gets plied up into various knitting yarns, and that works very well.

However, that yarn tends to be a bit fragile to use as warp without sizing.  (Perhaps someday, I will be a good enough weaver to adjust my loom so that I can weave with such a soft warp yarn, but not today.)

What works is worsted spun 10s (5,600 ypp) spun "hard" at ~ 14 tpi. Shit!! I was only putting 17 tpi into 40s (22,000 ypp) and calling them "hoisery singles".   The hard 10s come off the spinning bobbin like barbed wire, and must be promptly steam blocked.  Then, when plied as knitting yarns they are more tractable, but you may want to consider blocking them again before knitting.  As warp, they are  stronger, are stiffer, and easier to sley.

This is another case where the ANSWER was in The Big Blue Book (pg 383), but between the lines.  I swear the really good stuff in AA is between the lines.  He was a little like Dumbledore - he points one in the correct direction, and lets one discover the details on their own.

With my twist requirements going up about 50%, I need all the flyer/bobbin speed that I can get.  Thus, I am back on the  Alden Amos #0 competition flyer running at about 4,000 rpm, and am still producing less than 400 yards per hour. It seems a little mean to stuff 45 grams onto it, but with a 3-gang flyer-whorl, it  works. On the other hand, the drafting seems relaxed compared to the hustle of  the 600 yards per hour of the 9 tpt medium 10s that I have been spinning for years.

Look, and read on

Costco also sold The New Ivy Brand Vintage Classics with packaging stating that it was hand spun, hand woven.

Later, Costco  also did sell "Original, Weatherproof  Vintage" brand (made in Vietnam, not China!!)

I own some of both, and did not keep the packaging, from either.

Go to India, and look at their hand spinning frames.  You will need it for the next post!!

More spinning bobbins

Alden really did tell me very emphaticly, several times that whorls, flyer and bobbin should be have  "board cut grain".  That did not stop him from making spindle turned bobbins as in

where he supplied me with bobbins with board cut grain and that were spindle turned. 

  Thus, since then, I ( mostly) made my spinning bobbins form glued up blanks so that the ends of the bobbins (the whorls)  had board cut end grain.

This summer, I did some spinning on the patio, and noticed that over a period of weeks, the spinning bobbin which had been turned from old red oak salvaged from a kitchen remodel, had warped! I never had any problems with Alden's, or Ashford's board cut grain bobbin whorl's warping when I used them for spinning on the patio.  I expect that I could have prevented the problem with a different finish. (The red oak had a Danish Oil finish.)  (Also thicker whorls tend warp less.)  (Also, black walnut tends to be more dimensionally stable than the red oak. )

This was not the first time that whorls had warped on me, but this time, I took action. 

The new spinning bobbin for the AA#1 flier was spindle turned from a solid block of olive wood.

The bobbin above the flier is the oak bobbin that warped, The bobbin in the flyer is one turned in a few minutes.  No making the parts, and gluing up a blank. Certainly it is too wasteful of wood for a commercial operation, but it can be done quickly, without planning.  It good for repairs where a fast fix is needed.  It is just a matter of having a big (2.5" x 2.5"x 4.2"), dry,  block of wood around.

In the sun for a while, the diameter of the spindle turned whorls will change.  For single drive, or DD with slippage that does not matter.  For DRS, inserted twist can be adjusted by changing the flyer whorl. I have a graduated set of flyer whorls, so likewise change in bobbin whorl diameter is not a big problem.  Nevertheless, the groove in this whorl is a little different than that of the old red oak whorl, and it took about 3 hours to get the new olive bobbin spinning 63 m/gram from fine long wool at about 200 m/hr (3+ gr/hr).

It works well, but it sure sounds like an old industrial sewing machine.

Space Cloth

Just when you think you have seen everything!

'Space cloth' to revolutionise textiles industry

A designer and researcher has pioneered a new form of fabric which promises to revolutionise the textiles industry.Sonia Reynolds invented 'space cloth' – the first non-woven material made from yarn. It has a strong potential for use as a smart textile due to its unique structure with space to encase copper wiring, light emitting diodes (LEDs) and more.
Ms Reynolds brought the idea to Nottingham Trent University's Advanced Textile Research Group and is now undertaking a PhD in the subject to further develop the fabric's novel manufacturing process under the direction of Professor Tilak Dias and Dr Amanda Briggs-Goode, of the School of Art and Design.
Scientifically named Zephlinear, unlike traditional woven or knitted materials which are made by the interloping or interlacing of yarns, it is made by a newly established technique known as yarn surface entanglement.

Research shows that it is strongest and most efficient when created from natural yarns such as one hundred per cent wool, hair and wool/silk mixtures, though it can also be made from synthetic yarns.

Um; you know this stuff!  You have likely made this stuff - it is felting with yarn --it happens by accident in sloppy skeins, and on purpose in felting projects.

Costco had several styles of men's shirts made by The New Ivy Brand:

All had prominent packaging stating they were hand spun and hand woven.

I trust Costco to require accurate labeling.  Unless you want to accuse Costco as an accessory to fraud,  accept the above, as labeled.


I would not have accepted the material as hand spun without having tried to buy such a spinning "frame", and run into the export tariff.  And, remember that Shetland Harris Tweed is also hand woven.

Jerseys and Guernseys

See Patterns for Guernseys, Jerseys and Arans by Gladys Thompson, Page 5, line 12.

See L'Ouvre by E. Zola.  It seems that "Ouvre", as a name for "Jersey" dates only to Victorian Times.

And, yes, ouvre at that time could only be knit with techniques that could not be mentioned in polite society.

Dreaming

All men dream, but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make them possible.

T. E. Lawrence

Handspun and hand woven cotton!
Why is handspun and hand-woven wool so much harder?

Why do people who seem not to be moving their craft forward, complain about the speed that I move my craft forward?  Why do they complain about my progress without seeing what I have actually done recently?   I solve many of my craft problems, without posting them.  While, I do not see them posting any textile craft solutions at all.

Making sweaters is doing the same thing over and over.   Unless the successive sweaters are better, faster, or cheaper, they are repeats of previous experience, that do not add significant additional expertise.  If you want to claim years of experience, then you should be show a consistent progression toward  better, faster, or cheaper.  If you progress by taking classes, then you are gaining expertise, but you are not advancing the craft.  To advance the craft, we must dream by day.

Where are the other "dreamers of the day"?  We should track "dreamers of the day", for they are dangerous.  (Actually, I think they are rather a fun lot, full of ideas, and always seeking a better, faster, cheaper path to "Better, Faster, Cheaper".)  We dreamers of the day take Blaize to be our hero.  Then, we ask, what is the Noble thing?

Do we consider the "Yarn Harlot" to be a "Dangerous Dreamer of the Day"? No, she follows and reports recent trends and fads, with pleasant humor. She tells us that what modern knitters are doing is good.  She does not incite revolution, she calms.

The cotton above is a commercial product from India. During the Old Kingdom period, when Egyptians were making exceptionally fine linen, they were also importing cotton cloth of similar fineness from India. Thus, I do not feel bad about using fine cotton cloth from India.

Sponges

A while back, the Captain of the tall ship Alma, kept a place at Lake Berryessa, and he was a generous host.  However, over the door was a sign, "No Sponges!"

The purpose of the  Lake Berryessa place was the weekly party, and everyone was expected to contribute to the party.   Captain would buy truckloads of booze, and everyone was welcome to drink as much beer and rum as they wanted - but they had to contribute to the party. The Captain had toys, but all the boys had to make sure all the toys were all in perfect working working order and gleaming with fresh wax jobs when the girls arrived on Friday evening.

Here, I have tolerated Sponges!  Sponges carp and criticise about the pace of my research as to how to weave hand spun without contributing to the research.  If they want to complain about how slowly the research proceeds, then they can either tell me the solution to the problems; or, send me a stream of checks to allow me to spend more time on weaving.  If they criticise without  helping the project, they are just Sponges.

Oh yes, and by the way there is a very interesting CPW in the Florence Pioneer Museum.  Note the wheel /bobbin ratios.

Seduced by the Dark Side, I was!

Many times, I have stated that combed top and (pin drafted) roving from mills is more difficult to spin and I have noted that yarn, handspun from mill processed fiber is not as strong or durable as yarn handspun from traditionally processed yarn. Still, I acquired a pile of mill processed fiber and spun a lot of 5,600 ypp worsted singles.  I had a big bin of these singles and they got used for everything.  Along the way, I checked to see that the resulting yarns were stronger than mill spun yarns.  That was the wrong approach. I should have made sure that the singles/yarns spun from mill processed fibers were as strong as singles/yarns spun from fiber that i scour and comb.

Yes, mill processed fiber is fast, easy, and may actually be less expensive than raw fleece.

The dark side is that yarn from mill processed fiber is not as strong and durable.  The Darkside is that unless you are going to dip your handspun warp in steam heated sizing solution prior to warping the loom,  then you are likely going to have to skip mill processed fiber for your warp.

I knew hand scoured fiber  (including processing by folks like Morro Bay) resulted  in stronger singles.  I knew that hand carded and hand combed fiber produced better singles.

Nevertheless, I thought that mill processed fiber would be "good enough". I let the Darkside seduce me.  This is something I need to unlearn.

Today, I think one reason why we do not see hand spun, hand woven cloth is that people try to hand spin mill processed fiber into warp, and it does not work.  This was a useful thing to learn.

Good stuff

 Hand spun, worsted 10-ply Aran

The yarn is not designed to be easy to knit.  The yarn is designed to have very high fill, so as to produce a fabric that is exceptionally warm,  durable, and very comfortable to wear.  Knitting this yarn into the desired fabric is a ferocious effort!  On the other hand, the yarns that are easier to knit do not produce the same fabric!  Do I want "easy to knit" or "warm,  durable, and very comfortable"?

What do you want?

I had to spend days reworking the needle tips to find a shape that allowed knitting this fabric at a good pace.  I had to modify my knitting technique. I had to put padding on the knitting sheaths.  The fabric is worth all these efforts.

The shape of needle points is important, and different yarns require differently shaped needle points.  And some projects are much better knit with blunt, curved needles, that are rotated into the fabric.

  

"Bombproof" fisherman's socks being  swaved from

 worsted 5-ply, sport-weight, high-ply twist (non-splitty)  handspun from Romney fleece.

Such needles (pricks) require a knitting sheath optimized for this technique.

Good products may take more effort!  I would rather put in more effort and get a better product than just do it the easy way for a lesser product.  How about you: Do you want easy?; Or, better?

I have been spinning, and knitting 4, 5, 6, 7, 8, 9, 10, 12, and 14 ply yarns for some years now; and, knitting swatches (socks, etc,) to figure out how the various yarns behave.  I have plied yarns firmly and softly, and cabled them as 2x2, 2x3, 3x3, 3x2, 4x2, 5x2, and etc to see how each of these yarns behave as fabrics.  I have compared my-spun with mill spun.  I know how to spin/ply yarns that are not splitty; and, I know how to produce yarns that are easy to knit.  Been there. Done that!

Mills need to sell "easy to knit yarns" because not all of their customers are superior knitters. Consider for example how many modern knitters are so dedicated to their craft, that they make their own needles.    Likewise, not all hand spinners, are superior hand knitters. And, being more members of a social club, than craftsmen seeking mastery, they are not willing to make the effort to spend  YEARS of working out how to spin and knit a particular, exceptional fabric.  They do not follow paths to fabrics that require special tools and special skills to produce. Special fabrics also require the insight to predict even the existence of the fabric. 

One gets to special fabrics by beginning with the end in mind.  One does not just stumble onto special fabrics,  rather, one must visualize the tools and skills that will be required for the fabric, before the combination of  tools and skills required for a particular fabric can be developed.  If you are buying your tools, materials, and skills at "Stitches", then you are not going to get to "exceptional fabrics".

Most modern spinners use commercially available spindles and spinning wheels, so they are not going to spin yarns that are difficult to spin on modern commercial spinning wheels (e.g., worsted spun, 5,600 ypp singles).   Most modern knitters use commercial needles, so they are not going to knit fabrics that are difficult to knit on such commercial needles. In contrast, I spend years making the spinning tools that I need to spin exceptional yarns that are difficult to spin on modern commercial wheels. AND,  I spend years making the knitting tools that I need to knit fabrics that are difficult to knit with commercially available knitting needles.

Exceptional yarns and fabrics are outside of the social boundaries of modern spinning groups (e.g local guilds and Ravelry).  Mostly, modern spinning and knitting is about being a member of the social group, rather than of producing exceptional textiles.

Those that cannot do, criticise.

How many of  you have actually worn objects of hand spun worsted 10-ply Aran yarn so that you have a basis of comparison?  How many of you have seen cakes of handspun worsted 10-ply Aran yarn so that you have a basis of comparison?  How many of you have made objects of 10-ply Aran yarn, (and worn them in a good, long, hard, cold rain?)  The truth about seaman's sweaters is only found in  a good, long, hard, cold rain!   If I was knitting objects for Siberia, then in 5 of the plies, I would have used a finer wool, spun woolen.  That fabric is not as durable, but it is softer, and warmer for the weight.  It is also harder to knit, and more likely to felt/shrink when abused.

Going to all woolen, produces a yarn that is much easier to knit, but not nearly as durable and  the high country (and Siberia) have long winters.

I had to sit in the snow, and watch the whole parade.

If stuff is good, you will need more than one.

Those 10 cakes have about 20,000 yards of singles in them.

The spinner's creed

What does a good spinner need to know?

aspirational - be able to name and replicate any natural fiber yarn or thread, including those in suiting, shirting, coating, undergarments, and other fabrics, both archaic and recent.

The core of a spinner's craft is being able to make the particular, and named yarn, that is desired.

A spinner should be able to estimate/ budget materials required to make a particular batch of yarn, the tools required, other resources required, and the total spinning labor.

Things a spinner stands ready to do, include:

• grade wool as to spin count with a twisty stick / modern tools
• sort and scour a fleece  ( http://www.infovets.com/books/smrm/A/A988.htm)
• comb wool
• card wool
•  name yarns,  particularly including grist  (http://www.swicofil.com/companyinfo/manualyarnnumbering.html, etc )
• spin wool at its spin count 
•  ply and cable yarns
• care, maintenance, and setup of single lead, and double drive spinning wheels
• design and specify spinning wheel whorls
• prep spin camelid fibers finely 
• prep and spin cotton, both woolen style and worsted style into very fine thread
• prep and spin flax into fine linen threads 
• prep and spin hemp into thread
• and, of course, spin silk finer than frog's hair.
• prepare fiber and yarns for dye operations
• dye to desired colorway

Compared with the above, the little bit of history in a "Master's Spinning Course" is trivial and will be picked up along the way. (I figure basic spinning requires about 6,000 hours of practice, and master's level spinning requires about 14,000 hours of practice.) I find skills to be highly transferable between fibers.

Spinning is about spinning, not history.  If you want history, go look at the fabrics depicted on recently discovered Classical Greek sculpture (not Roman copies) showing the very fine yarns/fabrics that were produced in Classical Greek times (phys.org , but I cannot put my finger on it at this time.)  The Classical Greek stuff sets a much higher bar for the "Old School" production of textiles.  

Alden Amos, revisited

Alden Amos', Big Book of Handspinning (2001) (aka Big Blue Book, BBB) is the best book on hand spinning wool.

At one time, I thought there were as many as 9 glosses in it, but no actual errors.  this puts it far ahead of every other book on hand spinning, which all that contain actual errors.  For somebody wanting to learn to spin ordinary yarns, BBB is the best book,  and every hand spinner should have a copy.

Glosses that I recognize today include:

• It does not discuss practical mechanisms for differential rotation speed (DRS) flyer/bobbin assemblies.  In truth, 3- gang whorls work very well with 4" bobbins/ 500 m skeins at grists down to 10 m/g,; and, gang whorls are not required for spinning skeins of 500 m weighing 10 grams or less.
• It dismisses the value of high-ply yarns (e.g., 5-ply, 6-ply, 10-ply).  In contrast to what the BBB says, high-ply yarns have virtues for knitting very warm and/or very durable fabrics with a pleasant hand, drape, and touch.  High-ply yarns knit up faster, and spinning is faster than knitting.  While BBB gives the best directions for basic plying, it does not address producing 5-ply and higher yarns.
• Double treadle/ fast spinning is more healthy than spinning at a lower level of activity. 
• It does not discuss how to spin fine threads. I believe that any spinner with a good teacher should be able  spin super-fine threads of 40,000 m/g (44,000 ypp) within a few months of starting spinning.  The elements of learning to spin fine, are knowing it can be done and  having good tools that are properly set-up.  DRS makes fine spinning much easier, starting to spin fine on a ST wheel is an exercise in frustration. that become perfectly easy after some practice on a DRS wheel.  Why?! Because fine singles can be plied into fine yarns with both puns intended.
• There is limited discussion on the handling/management of very fine singles.
• It understates how fast a motivated spinner can actually spin. 
• Limited discussion of accurate use of, and correction factors for, wraps per inch (WPI).
• Limited discussion of accelerators.

All the glosses are only of interest to advanced spinners, and do not detract from BBB's value for beginning and intermediate spinners.  

Spades

When I came to knitting for warmth, I was told loudly, and firmly by "experienced knitters" that commercial yarns knit on circular needles were the correct program for knitting warm objects. I thought not. (Read as: "Thousands of swatches knit from commercial yarn using circular needles, and tested".)

At first, I thought commercial yarns knit with long needles (per EZ's note in GT ) were THE answer!! Then it was clear the knitting sheaths were very much a part of the solution; and,  I had to make knitting sheaths. Then it was clear that there were multiple distinct knitting skills that had to be learned - - Better to practice on cheaper, mill spun.

Yes, much of my skill is making tools!

However, those tools (or any tools) are worthless without the skills to use them! 

Thus, another part of my expertise is to visualize, develop and refine the skills required to obtain significant benefit from a tool kit.  Without skills, tools are just a pile of junk!!  A tool is not a tool, until one has the skill to use it.  With skill, a simple piece of wire becomes a knitting needle!

I tested commercial yarns for a while for a while, and after a few years, decided that handspun was likely just as warm , and I should test handspun. It took a while to learn to spin. It took a lot of intercomparisons between handspun and commercial to show the various virtues of handspun.  However, my spinning was still slow, and commercial yarns were still the practical approach for knitting the stuff that I wanted.  Yes, I knit a lot of commercial yarns because I did not have a teacher and commercial yarns were a very good practice material.

Working out the mechanics of DRS (spinning) took a long while, which produced better handspun, and it convinced me that high-ply yarns had GREAT advantages, but spinning fine singles was still slow.  So, for my functional gear, I was still knitting mill spun (with long needles and knitting sheaths!)  Then, I had to work out the details of accelerator wheels to sped up my spinning.  (It took 5 generations of prototypes to get it up to current speed.)  Prior to a well working accelerator, high-ply hand spun did not seem very practical.

In fact, today, I can run my Ashford Lace Flyer at over 3,000 rpm - something I did not think was possible even only 5 years ago.  However,  one of my DRS flyers running at the same speed is enormously more productive for ordinary fine plies.  On the other hand, I would be delighted if someone would please show me how to use an ordinary Ashford Lace Flyer to produce worsted spun, 5,600 ypp singles at a hank per hour.  I would love to learn how to do that!

While I was spinning 5-ply sport weight, by the fall of  2006, much of my handspun production went to testing to be sure that it really was as good as commercial for various uses.  And, there was that economic issue of: "Can handspun be reasonably priced?"

The first part of this blog is about knitting sheaths, and their power!  The first posts were about long needles and knitting sheaths, and I still consider knitting sheaths to be the most powerful tool in hand knitting.  Knitting sheaths work just as well with mill spun just as well as with hand spun.  Since I did not have a teacher, and was working everything out as I went, it was cheaper and easier to work with commercial yarn. I have a great deal of very good outdoor gear that I knit from commercial yarn.  It is gear that I would trust to keep me warm in Arctic/polar conditions for weeks or months at a time.  I do not find it durable enough to trust to keep me warm for years under Arctic/polar conditions -- commercial yarns are not durable enough, so that maintenance and upkeep on the objects would be too great.  That is what can make HANDSPUN cost effective! High-ply, handspun yarns can be so much more durable that over the long run, hand spun can be about the some price as mill spun, because as produced today, mill spun is not as durable or as warm for the weight.   And the big cost on outdoor wear is knitting and repair /maintenance.  More durable yarn up front is cheaper than reknitting.   (I am still doing economic analysis from the viewpoint of a 15th century fisherman.)

 Who else is testing sweaters that contain 20,000 yards (18,000 m) of singles?  Such objects have virtues, but you cannot see those virtues, unless you can produce such objects in a practical manner. .  I see those virtues through the window of the tools and skills that I have developed over the last 18 years.

Fat

More evidence that 'healthy obesity' may be a myth

The term "healthy obesity" has gained traction over the past 15 years, but scientists have recently questioned its very existence. A study published August 18 in Cell Reports provides further evidence against the notion of a healthy obese state, revealing that white fat tissue samples from obese individuals classified as either metabolically healthy or unhealthy actually show nearly identical, abnormal changes in gene expression in response to insulin stimulation.
"The findings suggest that vigorous health interventions may be necessary for all obese individuals, even those previously considered to be metabolically healthy," says first author Mikael Rydén of the Karolinska Institutet. "Since obesity is the major driver altering gene expression in fat tissue, we should continue to focus on preventing obesity."

Some drink, some ply

I ply.

The results from last night, 4 cakes of 10-ply from hand spun singles, and the bobbins emptied to make the cakes:

I like the yarn for warm, comfortable objects. I knit this 10-ply yarn on US3 needles  (3.2 mm) . When I knit commercial (lo-ply) yarns into Aran weight objects, I used 18" steel needles, and it was fearsome work.  Now, I use 14" steel needles.  Between the lighter needles and more flexible yarn, the knitting  effort is much  less.

If you must deal with cold weather for extended lengths of time (e.g. professional need to be outside, all winter long) and one is a good spinner, then I think 10-ply is well worth the effort.  If you are just going to be outside for a few weeks or recreationally, buy cold weather gear.

Certainly, one can knit 2" by 2" swatches from such yarns into weatherproof fabrics with circular needles is a great deal of effort (said by some one that considers making handspun 10-ply, "reasonable").
