Designed by Sharon Schamber, multi award winning quilter.

I've used these since my Houston trip and find them indispensable.  My only grip is I forget they are inside my bobbin case and keep dropping them when I change bobbins!!

These magic little teflon bobbin washers stop your thread bird-nesting or just plain tangling.  You slip one inside your bobbin case - there is no right or wrong side - insert your bobbin and continue sewing as usual, except you won't have thread hassles. 

There are twelve washers in a pack.

Here's what the designer says about her product.
SEW EASY! These slick space age 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 bobbin and you're good to go! Fits all domestic machines. Designed by author, teacher and award winning quilter Sharon Schamber.

Package of 12. Tough and long-lasting.
