same fabric and threads as actual garments.
Fine-tune the tension as necessary.
Balanced tension:
The rows of stitches on the right side of the fabric are
straight and even. The looper thread forms the dual rows
of squares with diagonals.

thread crossing points.
Tighten the needle thread tension, and/or loosen the
looper thread tension to correct it.
