Felted (boiled) wool is all the rage so how about giving in to the inevitable. You could make a huge shawl and carefully felt it smaller. I wear shawls fequently indoors because our house is quite cold - a shawl is quicker to put on and off than a jumper. I have felted knitted mitts but found it very difficult to work out how big to make them initially so that they would be the right size when felted. They did work out ok.
Or I wonder if you could felt the yarn before you knitted it - that could affect the handle of the yarn differently than felting it after it's knitted or woven. If you were to dye it, then it would become felted then anyway.
I'm trying to do a bit of lateral thinking here.......
I've just seen Sally's bit which she wrote while I was still cogitating, but the same idea
