Each approx. 4 oz skein contains about 420 yards of richly dyed sock joy. Fiber content is 80% superwash merino, 10% cashmere, and 10% nylon for strength and durability. Gauge is 5-8 stitches to the inch; of course, your mileage will vary. Hand wash; lay flat to dry. Please note that all of our skeins are unique; for best results, alternate skeins.
