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