Adjust the Needle Thread Tension
for a
Zigzag
Stitch
For an ideal zigzag stitch, the bobbin thread does not show
on the right side (Top side) of the fabric and needle thread
shows slightly on the wrong side (Bottom side) of the
fabric.
See the illustrations for correct appearance.
To match this appearance, adjust the needle tension.

Minimize the amount of needle thread visible on the
wrong side (Bottom side) of the fabric without causing
excessive puckering or causing bobbin thread to show on
the right side (Top side) of the fabric.
Results vary with fabric, thread and sewing condition.
