* 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

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
