ummmmm just sort of thinking aloud.. to felt wool you would lay it in a large plastic bag, add fairy liquid, warm water and then rough it up a lot, i wonder if you put it on inside out, took a sisal bath mitt and slopped on the fairy liquid and gave yourself a good old massage it might shrink and felt it a bit leaving the outside looking ok???? lol, like i said just thinking aloud and wondering... no insurance claims please
why not just wear them both together?
