This is 100% Soft Peruvian Wool, worsted weight, which we hand paint in our studio with non-toxic colorfast dyes. Each skein is 220 yards and weighs 4 oz. We wind each skein in a center pull "cake" for your knitting or crochetting convenience. This yarn also felts beautifully. If you need more of a color than what is available email us and we can dye more for you.
