This yarn is an exquisitely soft blend of 50% Tibetan yak down and 50% wool. The yarn is sport weight knit on US 3-5 needles or as needed to get gauge. Each 100 gram skein has 310 yards. To finish - gently block finished pieces using a spritz bottle to dampen fabric. Press gently into shape and dry flat. Care for garments by spot cleaning or hand washing cool water as necessary.
