What are felted socks or slippers?
Felting or fulling is the process of getting the little barbs on the surface of wool to interlock with each other. This creates a durable, almost wind-proof fabric that is very different from the knitted fabric. Felting is the process of converting yarn to felted fabric. Fulling is doing the same with a finished object. Fulling makes the finished object smaller. Read what makes wool felt here: http://www.peak.org/~spark/whywoolfelts.html.
