When all tensions are correctly set, the
needle threads (green and blue) are just
slightly visible on the underside of the fabric.
The looper thread (violet) is situated loosely
in between.
The right needle thread (green) is too loose,
causing large loops on the underside of the
fabric.
Set the green thread tension to a higher
value.
The needle threads (green and blue) are set
too tightly causing folds in the fabric.

lower value.
