Bobbin thread sits underneath your design and affects tension, smoothness, and how the back looks. Getting it right prevents a surprising number of problems.
Choosing the Right Bobbin Thread
- •Use a lightweight 60- or 70-weight bobbin thread for most embroidery.
- •White bobbin works for light fabrics; black for dark fabrics.
- •Pre-wound bobbins save time and wind more evenly than self-wound.
- •Match the bobbin case tension to your thread weight.
- •Keep bobbins clean and lint-free.
How to Get It Right
- 1Wind bobbins at moderate speed for an even fill.
- 2Use the correct bobbin weight for your machine.
- 3Check that bobbin thread shows about one-third on the back of satin columns.
- 4Replace the bobbin before it runs out mid-design.
- 5Clean the bobbin area regularly.

On a satin column, the back should show roughly one-third bobbin thread and two-thirds top thread. That ratio means your tension is balanced.
