Felted Slipper Boots Pattern made from recycled wool Sweaters. No knitting or crochet skills needed, you simply CUT - SEW - then FELT IT! Super Easy Pattern. A great way to use an old Wool Sweater that is not being worn anymore or use recycle thrift store sweaters. This Pattern makes Woman's size M-L. Small size can be achieved by cutting pattern just a bit smaller or felting for a longer time. Learn my top secret (shhh) method of adding a non-skid sole to the bottoms. A great way to reuse and make a unique gift. Super item for selling at Craft fairs, farmers market, Etsy, etc. Embellish them any way you like! Make them look like Mukluks, Uggs, etc. BASIC SKILLS NECESSARY Basic sewing with a sewing machine.
