Adjust the Needle Thread Tension for
Straight Stitch
• Correct tension
Needle thread (Top thread)
® Bobbin thread (Bottom thread)
® TOloosen
_) 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
