Wool

East Friesian sheep produce a good amount of wool. As crafters and fiber artists, it can really be a delight to use East Friesian wool either alone or blended with other fibers. A medium textured wool suitable for cardigans, outwear, and house goods, it has micron width of around 29-33, and a good staple length between 4-6 inches. If you are a spinner, you will be interested to know that it has a fine crimp. The resulting yarn has a fair bit of bounce to it, making it great to use as a DK weight or heavier yarn weight.
