4.10 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 ruffing and thread breaking.
Proper setting
If the tension of needle thread and hook thread is identical, the thread
interlace lies in the middle of the sewing material.
Adjust the needle thread tension so that the desired seam pattern is
achieved with the lowest possible tension.
