La Pierre Magic Bobbin Washers Pack of 12 Snap in Bobbins

These slick Teflon washers eliminate the backlash in the bobbin when changing directions at high speed. 'Backlash' creates "birds' nests" in free-motion quilting and embroidery. Just drop a LITTLE GENIE in the bobbin case, replace the bobbin and you're good to go!

Fits most domestic machines.
