ok, you know what dread locks are right? well think of doing tht to yarn, it makes whatever youve made with the yarn into a felt like fabric.. thts not exactly the best way to put it but its the only way i kno how to get the idea across...lol hope tht helps
I think what nancydeez is asking is if the yarn is superwash wool, or not. If it's not superwash, then it can be felted. But if it says "Superwash", "New Wool", "Treated" or "non felting", it probably won't felt. From the pic, I looked up the yarn on Ravelry, it looks like it might be Superwash. http://www.ravelry.com/yarns/library/lane-borgosesia-knitaly
