Adjusting the Needle Thread Tension
e Choosing the Correct Tension
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 stitch, you will
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.
Results depend on:
- stiffness and thickness of fabric
— number of fabric layers
— type of stitch
Needle thread (Top threaq)
Bobbin thread (Bottom thread)
Higher numbers (Tighten)

¢ Tension is too tight
The bobbin thread shows through on the top side of the
fabric and it will feel bumpy.

Solution: Lower numbers (Loosen)
e Tension is too loose
The needle thread shows through on the underside of the
fabric and it will feel bumpy.
Turn the dial to the right to tighten the needle thread
tension.
Solution: Higher numbers (Tighten)
