Wool Yarn — Heritage Breed, Regenerative & Non-Superwash | String Theory

Wool does things no other fiber does — holds heat when wet, takes dye like a painting, and remembers the shape you give it. We carry it in many forms, from many places. You will find regeneratively raised US wool from Mitchell Wool Co, non-superwash heritage-breed wool from Wooldreamers spun from Manchega sheep in Spain — the same flocks whose milk becomes Manchego cheese — GOTS-certified organic superwash from Neighborhood Fiber Co. for socks that need to survive the laundry, and an angora wool blend from Handspun Hope, where Rwandan women earn a living wage spinning by hand. The right wool for every project.
