Magna-Glide is a pre-wound bobbin from Fil-tec using Glide, the 40 weight polyester thread you already know and trust, and wraps it around their patented magnetic-core. This creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. The magnetic-core prevents backlash or over spin and eliminates the need for backlash springs.

Magna-Glides are produced using the top Glide colors, giving you a perfect match on the bottom and top of every piece you stitch.

Due to differences in computer monitors and printers, the colors displayed above may vary slightly from the actual product. We always recommend comparing colors using your Glide Color Card. Looking for a way to keep track of which Glide Thread colors you already own so you aren’t buying duplicate colors?

For your Magna-Glide prewound bobbin to work accurately, always insert the magnet down into the case.

Remember to remove the anti-backlash check spring from the metal bobbin case prior to use. Failure to do so may lead to tension problems and thread breaks.

    New Favorite Bobbins! My on-board bobbin winder recently stopped working, and I found these magical pre-wound bobbins. It was nerve-wracking to remove the spring from my bobbin case, but these bobbins are so fabulous I'll probably never bother to wind a bobbin again! The color is great, too. It's a versatile shade of gray that looks good on nearly any fabric.

    Love this color! I love this color, Cool Grey 3. Being a neutral it blends with just about any fabric I have ever used, this is my go to color if I am just not sure of what I want to use.

    My go to bobbins The Cool Grey 3 is my go to color for bobbins, I find I am using this color about 85% of the time on my quilts, As with all the Magna Glide pre-wounds they work so well that I never really have to worry about my tension at all. The fast shipping time is just an added bonus too!

    Great bobbins! These bobbins are great! I was winding my own, when someone suggested I use these instead. What a difference!

    Love these! You can't go wrong with magna-glide bobbins. They work perfectly with Glide thread and take all the hassle out of trying to wind your own bobbins. They produce beautiful stitches. Just remember, because of the magnetic core to remove your backlash spring.
