Balancing needle thread tension
The needle thread and the bobbin thread
should interlock in the center of two layers
of fabric in straight seams.
Set the desired number of the thread
tension dial at setting mark.
Loosen the needle thread tension by
moving the dial to a lower number.
Tighten the needle thread tension by
moving the dial to a higher number.
Thread tension for zigzag sewing
To obtain better zigzag stitches, the up-
per tension should be slightly weaker
than in the case of straight sewing. The
upper thread should appear slightly
on the reverse side of the fabric.
