Each approx. 4 oz skein contains about 420 yards of richly dyed sock joy. Of course, this yarn also makes lovely hats, cowls, shawls, and sweaters. Fiber content is 80% superwash merino, 10% cashmere, and 10% nylon for strength and durability. Gauge is 7-8 stitches to the inch on US 1-3 needles; your mileage may vary.
