Black Sewing Machine Spool Pin Felt Genuine Wool

This thick, high quality black spool felt is made of genuine wool. The center hole is cut small so it fits snugly around the spool pin to ensure that it doesn't spin with the thread but instead allows the thread spool to spin independently. 1" in diameter and approx 1/8" thick, price is for one felt. Universal, compatible with most sewing machines. Spool felts have many benefits; they minimize friction allowing the spool to turn freely and reduces backlash, they also help to protect your machine's finish. They can also be used on machines with a removable drip pan to help reduce vibration between the pan and the thumb nut (this includes the Singer 221 Featherweight, 301A, 401A, 403A, 404, 500A, 503A, etc)
