How to use it

  1. 1Check your machine’s bobbin size before ordering. Style L fits most commercial embroidery machines; Style M fits only machines built for it.
  2. 2Run the side type that works best in your machine with the least downtime. No one type is right for every machine.
  3. 3When you switch to magnetic core bobbins, remove the anti-backlash spring from the bobbin case.
  4. 4Re-check bobbin tension after changing bobbin type or brand. Sideless bobbins may need more tension than sided bobbins.

Frequently asked questions

What is the difference between Style L and Style M bobbins?

Size. A Style L bobbin is about the size of a nickel, and a Style M (sometimes called a jumbo bobbin) is about the size of a quarter. The letters do not stand for large or medium, and M bobbins only fit machines built for them.

Do I need to change anything to run magnetic core bobbins?

Yes. Remove the anti-backlash spring from the bobbin case for best results.

Why use continuous filament polyester bobbin thread?

It makes less lint than spun thread, which keeps the bobbin area cleaner.
