Website description:

“Soft bulky singles of 100% Icelandic Sheep Wool. 480 yards/lb. Warm, light, long wearing, and water resistant. Spun of the dual coated fleece, the outer fibers (tog) provide loft, wear resistance and luster. The undercoat (thel) is fine, provides warmth and softness. When spun together the blend is somewhat like a wool mohair blend. The yarn is fairly non elastic, drapes well and won’t stretch out.”
