For Straight Stitch
The ideal straight stitch will have threads locked between the two layers of
fabric, as shown above, magnified to show detail.
If you look at the stitch, front and back, you will notice that there are no
gads, that each stitch is smooth and even.
When adjusting top thread tension, the higher the number, the tighter the top
thread.
Choose the Correct Tension:
The best tension will depend on;
the stiffness and thickness of the fabric
the number of fabric layers
the type of stitch
