Adjust the Needle Thread Tension for Zigzag
Stitch
For an ideal zigzag stitch, bobbin thread does not
show on right side of fabric and needle thread shows
slightly on wrong side.
See the illustrations for correct appearance.
To match this appearance, adjust the needle tension.
• Correct tension
Right side of fabric (Top side of fabric)
Wrong side of fabric (Bottom side of fabric)
Minimize the amount of needle thread visible on the
wrong side of fabric without causing excessive
puckering or causing bobbin thread to show on the
right side of fabric.
Results vary with fabric, thread and sewing
conditions.
• Tension is too tight
(_) Right side of fabric (Top side of fabric)
Wrong side of fabric (Bottom side of fabric)
Corner of each zigzag pulls together on the right
side of fabric.

• Tension is too loose
Q Right side of fabric (Top side of fabric)
Wrong side of fabric (Bottom side of fabric)
The needle thread loops through wrong side of fabric
and is pulled almost together.
