This wool comes in only one color. Dark. It’s a hardy medium wool, with plenty of bounce and a crisp toothiness that lends itself to hardwearing textiles with oodles of definition. The sheep themselves were developed out of a cross between two major breeds that inhabited the Netherlands. Drenthe Heath sheep have grazed the same pastures since the beginning of the Neolithic in about 4,000 BCE. The later developed East Friesian Milk sheep was presumably brought in to increase the dairy production of the local landrace. The resulting Zwartbles is a very large and docile animal, with a white blaze down the face and white socks, and today is mostly kept as a heritage milking breed.
