The yarn is 6-ply sport weight. The construction is cabled 3 X 2-ply. Two plies are always gray Cotswold. This gives a "silver sheen" to fabric. Then, two plies are white and two plies are brown. The brown accentuates the silver sheen. Two plies are fine wool and two plies are "Shetland". When the Shetland is white, then the brown is Rambouillet. When the white is Cormo then the brown is Jacob (very like Shetland). Thus, there are always 4 plies of high luster wool in the yarn and 2 plies of finer, lower luster wool to contrast. Each yarn ball is ~ 2 oz. All plies are spun worsted. About half of the plies are already spun.
The sweater will be knit in round, on 2.38 mm gansey needles. The fabric is smooth and dense but elastic. Garment will be a basic blouse, Plan 1 from Knitting in the Old Way.
