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.
• Correct 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.
• Tension is too tight
