Bobbin Guide

Which Bobbin Should You Buy?

Bobbin thread does a lot of quiet work — it needs to run cleanly underneath whatever's happening on top, whether that's dense embroidery, quilting, or everyday garment sewing. Picking the right weight and finish keeps tension even and cuts down on thread breaks and bird's nests.

Here's a rundown of the bobbin thread lines we carry most often, and what each one is best suited for. Still not sure which to grab? Reach out and we're happy to help you match it to your project.
