Wedgewood Fibers makes this superb sock weight yarn from 75% superwash wool (for warmth) and 25% nylon (for durability and breathability). Available in unique, hand-dyed colorways, this yarn is oh-so-soft and lovely. Each skein is made in Seattle and is 3.5 ounces (100 grams) and 237 yards (217 meters). This fiber is hand-dyed with acid-fast food dyes in a smoke-free home. It is pre-washed before sale to prevent bleeding, but some darker richer colors may have some slight runoff. Fibers are technically machine washable and can be tumbled dry on low, but hand washing and laying flat to dry will help preserve your work.
