Most machines come with recommended starting points. For example, on the Brother PE770, set the tension dial to level 4 or 5. This baseline helps ensure your stitches begin at an optimal tension. Before making adjustments, run a test stitch on a scrap piece of fabric with the same thread and stabilizer you plan to use. Observe the stitch quality carefully, look for loose loops, puckering, or puckered fabric.
Run Test Stitches and Observe Stitch Quality
After the initial test, evaluate the stitch formation:
- If stitches are loose or show loops on the underside, tighten the tension by turning the dial clockwise in small increments (e.g., 0.5).
- If stitches are puckered or the fabric pulls excessively, loosen the tension by turning the dial counterclockwise.
Adjust gradually, testing after each change to see immediate effects. This slow incremental approach prevents over-tightening, which can cause fabric puckering or thread breakage.
Check Stitch Alignment and Finalize Settings
After each adjustment, inspect the stitch alignment and appearance. Ensure the upper and bobbin threads are balanced for even, smooth stitches. When satisfied with the tightness, no loops, puckers, or loose stitches, record the setting. This becomes your standard tension for similar projects.
