Needle^Thread Tension

Correct tension is important be­

cause too much or too little will

weaken your seams or cause your
fabric to pucker. Make a test sample
with the fabric and the thread you
plan to use and examine it. A well

balanced stitch, as shown in illustra­
tion A, will have the needle and

bobbin threads locked between the
two layers of fabric with no loops on
top or bottom and no pucker. The
tension dial regulates the degree of
tension on your needle thread. Set it

according to the type of thread and

fabric you use. The numbers on the

dial eliminate guesswork.

If the fabric puckers B, decrease

tension. If the stitches in your test
sample look loose C, increase

needle-thread tension.

» To decrease tension, turn dial to

lower number.

® To increase tension, turn dial to

higher number.
