Using cones for color matching bobbins
makes it much easier since you can see
the thread directly with larger images.

Magna-Glide Delights are 40-weight pre-wound magnetic bobbins. They feature a patented magnetic core designed to ensure consistent thread delivery and perfectly balanced tension from the first stitch to the last.

Remove the Check Spring: To ensure perfectly smooth tension, you must remove the anti-backlash check spring from your metal bobbin case before using magnetic bobbins.

Orientation: Place the bobbin into your bobbin case with the magnetic/lined side facing down into the case.

Sizes Available: Magna-Glide bobbins come in Class L (often used in Janome, Juki, or domestic embroidery machines) and Class M (usually used in longarm quilting machines and commercial embroidery machines).
