Correct tension for rolled hem
*
The illustration shows sewing result with correct
tension settings.
Set the changeable thread guide at the lowered
position.
Other settings are same as the 3-threads rolled hem
(See page 76).
However, tension adjustment may be required de-
pending on the type and thickness of fabric and
threads being used.
Make a trial sewing with the fabric and threads you
wish to use to obtain in the best results by adjusting
tension.
