Adjusting the Thread Tension

The tensions of the upper thread and of the bobbin thread (thread tension) should be adjusted so that they
are equal.

Thread tension

You may need to change the thread tension,
depending on the fabric and thread being used.
■ Correct thread tension
The upper thread and the bobbin thread should
cross near the center of the fabric. Only the upper
thread should be visible from the right side of the
fabric, and only the bobbin thread should be
visible from the wrong side of the fabric.
