How I felt hats
Step by Step Felting a Hat
I will try to intelligently take you through the process of one of the ways I use to felt an alpaca fleece hat. Some of the materials I use are a small sized beach ball (called the resist); a stand for the beach ball which could be a large glass jar; or a large empty coffee can or one gallon empty can; a large pair of tights or pantyhose with the legs cut off leaving enough room at the cut ends to tie the top of the legs together; saran wrap; towels; dish soap; needle punch tool; wash board or anything that can bring friction to the felt; tweezers to pluck out the grass left in the fleece; hat forms; fleece; wool; yarns; and a tray to work in and not spill.
Be prepared to spend at least four hours on this project. You can break it up by doing the hat to the point of drying, take a break while it dries, then do the finish work which is plucking, applying the inner liner, applying the outer band and then a flower, button or embellishment of some kind.
