Magna-Quilt Style M Prewound Bobbins (10 pack), Fil-Tec Details

Product Description

Fil-Tec's Magna-Quilt prewound bobbins are a high quality Egyptian long-staple cotton. The patented magnetic core prevents backlash creating consistent stitches and eliminating the need for a backlash spring. (If your bobbin case has a backlash spring, remove spring before inserting this bobbin.) This trouble free bobbin reduces lint and residual build up in the bobbin case. Always insert the magnet down into the metal case. Each bobbin contains 135 yds of thread. Each container comes with 10 bobbins. Made in the USA.

Magna-Quilt Style M Prewound Bobbins (10 pack), Fil-Tec

Using a long arm is so much easier with pre-wound bobbins. Magna-quilt is the bobbin of choice, every time.

Magna-Quilt Style M Prewound Bobbins (10 pack), Fil-Tec

My Moxie longarm machine seems to like these prewound bobbins. So until Moxie tells me otherwise, I like them too. I get more miles out of prewound bobbins, which means less bobbin changes. I generally use white or off white for all my quilting.

Magna-Quilt Style M Prewound Bobbins (10 pack), Fil-Tec

The magna quilt bobbin prevents the over spinning of bobbin thread thereby preventing extra loops and nests on the backing of a quilt. The tension seems to be different at the beginning of the bobbin versus the middle and end. But I think it is worth it to use them bc it alleviates other issues and seems to provide pretty consistent tension throughout the project.

These bobbins run smoothly in my Gammill Longarm machine and the stitch looks really good.
