Thread tension

The tension of the thread will affect the quality of your
stitches. You may need to adjust it when you change
fabric or thread.
Memo
● We recommend that you do a test sample
on scrap of a fabric before you start to sew.
■ Correct tension
Correct tension is important as too much or too little
tension will weaken your seams or cause puckers
on your fabric.

Loops will appear on the surface of the fabric.
Note
● If the bobbin thread was incorrectly

In this case, refer to "Lower threading" on
page 13 and rethread the bobbin thread.
