Adjusting the Needle Thread Tension

Straight stitch balanced tension

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 the seam, notice that
the stitches are evenly balanced.
q Needle thread (top thread)
w Bobbin thread (bottom thread)
e To loosen
r To tighten
When adjusting the 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
Tension is too tight
The bobbin thread shows through on the right side of the
fabric, and the stitch feels bumpy. Turn the dial to a lower
number to loosen the needle thread tension.
