Soft & cozy, Bernat Wavelength is a velvety, bulky weight yarn that knits & crochets quickly into fantastic sweaters, cardigans, hats, mittens, cowls & scarves. This unique yarn plies different color strands together, creating a marl. The colors gradually change throughout the ball giving projects a multi-hued fade effect. Easy to care for & comfortable to wear, Wavelength is spun with 100% acrylic. The yarn is both machine washable & dryable. It is also great for gift projects!
