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.
