Mastering Embroidery Thread Tension

Correct tension shows mostly top thread on the front and a little top thread on the back edges. This guide walks through the technique step by step, with practical tips to get clean results — and shows where a free tool like SewFlow fits in.

Step by Step

1. 1Stitch a test and look at the back — you should see about one-third top thread.
2. 2If bobbin thread shows on top, loosen the top tension.
3. 3If top thread loops underneath, tighten the top tension.
4. 4Adjust in small increments and re-test.

Tips for Best Results

• •The classic check: the back should look like a 'two-thirds bobbin, one-third top' column on satin stitches.
• •Re-thread before assuming it's a tension problem.
• •Different threads may need small tension tweaks.
