The Magic Bobbin Genie eliminates backlash and bird's nests on the underside of free-motion quilting, thread painting, or embroidery when changing directions at high speed. To use one, simply drop a Magic Bobbin Genie into your bobbin case, replace the bobbin, and insert it into your machine!
This package includes 12 Magic Bobbin Genies for size M (long-arm machine) bobbins.
