Design by Bev Galeskas. Cozy felt slippers for the whole family are quick to knit in double yarn and easy to felt. Size will vary some with different yarns, but can be controlled with careful felting and blocking. Made with a double strand of worsted weight yarn. Choose yarns that will felt easily and firmly. Use 2 strands of the same yarn held together or a strand each of 2 different yarns. A strand of mohair and a strand of wool make a good combination. Always test felt your yarns before beginning. Option for Fiber Trends Suede soles will add both traction and durability to your slippers.
