Thread tension

Together with the hook thread tension, the needle thread tension
influences the final seam pattern. With thin sewing material,
excessive thread tension can lead to undesired gathering and
thread breakage.
Proper setting
If the tension of needle thread and hook thread is identical, the
thread interlacing lies in the middle of the sewing material.
Set the needle thread tension so that the desired seam pattern is
achieved with the lowest possible tension.
