Adjust the Top Thread Tension
¡
Choose the Correct Tension
For Straight Stitch:
The ideal straight stitch will have threads locked between
the two layers of fabric, as shown left (magnified to show
detail).
If you look at the top and bottom of the seam, you will
notice that there are no gaps; that each stitch is smooth
and even.
When adjusting top thread tension, the higher the
number, the tighter the top thread.
Results depend on;
* stiffness and thickness of the fabric
* number of fabric layers
* type of stitch
