Adjust the Needle Thread Tension for
Straight Stitch
• Correct tension
® Needle thread (Top thread)
(D Bobbin thread (Bottom thread)
(3) To loosen
0 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 needle thread and bobbin thread of a seam,
notice that there are no gaps. Each stitch is smooth and even.
When adjusting 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
