This is a lovely, bright white Icelandic fleece. Locks are clean and free of most all vm, 5 to !0 inches long and are double coated. Double coated means that there are two part to each lock, a soft fluffy undercoat with coarser, longer guard hair. In this fleece the guard hairs are bright white as is the undercoat. Take care when separating the locks so as not to pull the two fiber types apart. There is some cotting but locks do separate.Traditional Icelandic yarn takes advantage of the soft warm undercoat for warmth and the longer guard hairs for strength and water proofing.Enjoy!
