This is a lovely Icelandic fleece from Queso Cabeza Farm. Locks are clean and free of most all vm, 6-8 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 white to creamy/buttery white and the undercoat bright white. Take care when separating the locks so as not to pull the two fiber types apart.Traditional Icelandic yarn takes advantage of the soft warm undercoat for warmth and the longer guard hairs for strength and water proofing.Enjoy!
