Adjust the Needle Thread Tension for a Straight Stitch
• Correct tension
1Needle thread (Top thread)
2Bobbin thread (Bottom thread)
3 To loosen
4 To tighten
The ideal straight stitch has threads locked between two layers of fabric, as illustrated (magnified to show detail). If you look at the top and bottom of a seam, notice that the stitches are evenly balanced.
When adjusting the needle thread tension, the higher the number, the tighter the top thread tension.
Results depend on:
-stiffness and thickness of the fabric
-number of fabric layers
-type of stitch
•Tension is too tight
1Needle thread (Top thread)
2Bobbin thread (Bottom thread)
3 To loosen tension
4 Right side (Top side) of fabric
5 Wrong side (Bottom side) of fabric
The bobbin thread shows through on the wrong side of the fabric, and the stitch feels bumpy. Turn the dial to a lower tension setting number to loosen the needle thread tension.
