ADJUSTING THREAD TENSION
When an even amount of tension is exerted on both threads, a smooth even stitch,
known as a balanced stitch, is produced.
C o r r e c t t e n s i o n i s i m p o r t a n t
because too much or too little will
weaken your seams or cause your
fabric to pucker. Make a test sample
with the fabric and thread you plan to
use and examine it.
A perfect, well balanced stitch (1),
will have the needle and bobbin
threads locked between the two layers
of fabric with no loops on top or bottom
and no puckers.
Too much, tension will produce a
tight stitch (2) which will cause the
fabric to pucker.
• To decrease tension, turn the dial to a
lower number.
Too little tension will produce a
loose stitch (3) which will cause loops
in your seam.
• To increase tension, turn the dial to a
higher number.
