Adjust the Needle Thread Tension for
Straight Stitch
•Correct tension
(_ Needle thread (Top thread)
(_) Bobbin thread (Bottom thread) (_ To loosen
(_) To tighten
The ideal straight stitch has threads locked between two lay- ers 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 num- ber, the tighter the top thread tension
Results depend on;
--stiffness and thickness of the fabric
--number of fabric layers
--type of stitch
