Adjust the NeedleThread Tension for Straight
Stitch
• Correct tension

To loosen
(_ 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
there are no gaps. Each stitch is smooth and even.
When adjusting needle thread tension, the higher the
number, the tighter the needle thread tension.
Results depend on:
-- stiffness and thickness of the fabric
-- number of fabric layers
-- type of stitch
