12 washers per package

Eliminate backlash and bird’s nests for good with Mega Magic Bobbin Genies — Teflon washers that slip into your bobbin case to smooth thread tension during free-motion quilting, especially when changing directions at high speed. Tough, long-lasting, and a must-have for longarm quilters.

Not sure which to choose? Here’s the breakdown:

• MG12 — M Class (White): For M-style bobbin cases. Used in most longarm quilting machines.
• BW12 — L Class (White): For L-style bobbin cases with a front-loading bobbin.
• DG12 — L Class (Dark/Grey): For L-style bobbin cases with a drop-in bobbin.

If you’re unsure which bobbin case style your machine uses, check your machine manual or look at how the bobbin is inserted — front-load slides in from the front, drop-in drops in from the top.
