I understand that you can only felt yarns made with animal fibers. However, I have a very soft alpaca, wool and silk blend yarn. (Make up is 55% wool, 25% silk, 20% alpaca). I know the silk won't felt, but would it prevent the wool and alpaca from felting? What type of fabric would you get felting this blend? Would it look like a mess or something cool and unique? Has anyone tried it?
