Thread tension for decorative stitching
When using a decorative stitch, a thicker thread is normally used
with a relatively thinner material. Then the thread interlace is not
buried in the material.
In this instance, the tension is set so the threads interlace on the
back side – see (2).
5.7.1 Setting the needle thread tension
The 3 adjusting wheels on the tensioning screw triangle determine
the needle tension.
On the basic setting, the top side of one adjusting wheel is flush
with the screw in the middle.
