Just knitting

A while back, I read an account of a Master Knitter who required his apprentices to "knit" for 5 years before he allowed them to purl anything.

Of course from a modern viewpoint that seems extreme.  

On the other hand, 500 years ago, a journeyman knitter would have passed through seaports where he would have seen seamen wearing Jersey knitting ("Ouvre", aka crossed stitch, right over left), knitting from Eastern Europe (crossed stich, left over right) and plaited fabrics where both kinds of crossed stitches are used, and the uncrossed knitting which is more popular today. 

As a craftsman, he would have thought about each of these knitting techniques on hand spun threads and yarns ranging from fine silk, and fine worsteds to the course woolens needed by stockmen working in the winter's cold and seamen braving the North Atlantic and Finnish Seas.

Knitting crossed stitches flat and in the round, require different techniques. (You are knitting a sock, and must change techniques when you get to the heel flap, and toe up knitting is harder to maintain consistent stitch pattern - you really do have to think 3 rows in advance.)

Knitting crossed stitches and uncrossed stitches in yarns of  different twist and grist with the speed required by a commercial enterprise, requires different tools. I would expect a knitting apprentices to make the needed tools for themselves.

Even if the Master was a good teacher that chose smart, nimble fingered, bright eyed apprentices; today, I think that the apprentices would have had to work very hard to master JUST KNITTING in 5 years.

Advantages of crossed stich knitting include greater elasticity - when stressed, crossed stich knit fabric will not stretch as far for the given stress, but it returns to it's original size and shape  better than knit fabric without crossed stitches.  And the fabric is ~ a quarter to a third thicker than fabric knit without crossed stiches from yarns of the same twist and grist at the same gauge. And, finer yarns often have more twist, and thus are more durable.  Crossed stiches allow knitting a warmer fabric from a particular yarn. And, the fabric surface is smoother, allowing the fabric to shed water better than fabric knit with uncrossed stitches from the yarns of the same grist and twist at the same gauge.

On the other hand, fabrics knit with crossed stitch techniques, take more effort, take longer, and are much more difficult to plan than just "uncrossed knit to fit".

I have not proven it yet, but I expect that a 1.5 pound "Jersey" knit from 1,700 ypp 3-ply yarn was as warm as a Yorkshire gansey knit from 5-ply weighing 2.2 pounds.  And, I am coming to expect that "cross stitch fabrics" are more durable than "fisherman's rib" for fabrics in points of abrasion such as sock heels, fingers of gloves, and such. And, think of the advantage of such warm, light, fabrics for a seaman with the clothing he needed for months at sea in a bag 8" in diameter and 24" long.  

Yes, today I think that much of  what we see in Gladys Thompson came after  mechanical spinning technologies (starting circa 1450) that were faster than drop spindles and the various driven spindles, and the "Enclosures" (starting circa 1604) that resulted in cheaper wool yarn. 

In short, I do not yet understand how sailors/fishermen on square rigged ships sailing from Norfolk (or St Helier, Jersey circa 1400 stayed warm.  The (wool technologies ???) that kept them warm are a puzzlement.

This is the most challenging and interesting problem I have come across in years. My knitting corner in the kitchen is a mess - I do not know how my wife stands it. My knitting costume is now overalls under a leather apron and 2" wide heavy leather belt supporting the knitting sheath. The overalls and leather apron form a stable base allowing the belt/knitting to be moved up and down and then be a stable base for my knitting pins.

There are at least half a dozen "swatches" (hats, socks, gloves) in process.  Needles range from 1.3 mm spring steel to 3.25 mm wood. Some of those needles are really long, and some are very short. The yarns range from 2,500 ypp worsted spun, 2-ply handspun to good old (https://www.macauslandswoollenmills.com/) 3-ply woolen.  

The different swatches use different muscles, as one set of muscles gets tired, I switch swatches.

Crossed stitch knit fabrics let woolen yarns show off a whole new bag of tricks.
