■ Upper tension is too tight
Loops will appear on the surface of the fabric.
Note
● If the bobbin thread was incorrectly
threaded, the upper thread may be too tight.
In this case, refer to "Lower threading" on
page 13 and rethread the bobbin thread.

■ Upper tension is too loose
Loops appear on the back of the fabric.
