These are pre-wound Size M bobbins, wound with WonderFil's 80wt DecoBob™ cottonized polyester. Size M is what most longarm and midarm machines take — check your bobbin guide if you're not sure.

Two things set these apart from cheap pre-wounds. There's no glue or wax holding the wind together, so nothing gums up your bobbin case. And the bobbin itself is reusable plastic-sided rather than disposable cardboard. The 80wt thread is deliberately fine: less bulk in the seam, and a matte finish that sinks into the fabric instead of peeking through from the back.

Machine-wound bobbins also carry more thread than you can get winding your own, and they wind evenly — which shows up as more consistent tension, most noticeably in embroidery.

The Christmas assortment covers the holiday palette, so your bobbin thread matches the top thread on seasonal projects instead of fighting it — which matters most on quilting that shows on both sides.
