Balancing Needle Thread Tension

z

Correct tension:

The thread tension is adjusted depending on

the sewing materials, layers of fabric and

sewing method.

* The ideal straight stitch has threads locked

between two layers of fabric, as illustrated

(magnified to show detail).

* For an ideal zigzag stitch, the bobbin thread

does not show on the right side (top side) of

the fabric, and the needle thread shows

slightly on the wrong side (bottomside) of the

fabric.

Thread tension for zigzag sewing

To obtain better zigzag stitches, the upper
tension should be slightly weaker than in
the case of straight stitch sewing.

The upper thread should appear slightly
on the reverse side of the fabric.
