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 depending
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.
