Wedgewood Fibers Bulky yarn is perfect for a quick crafting fix. The chunky weight works up in a flash, and the 100% superwash wool is warm, soft, and durable. This fiber is hand dyed with acid-fast food dyes. 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.
