If all the thread tensions are set correctly,
the needle threads (blue, green and red)
are almost invisible on the underside of the
fabric. The looper thread (purple) lies slack
between them.
The needle threads (blue, green and red)
are too loose and form small loops on the
underside of the fabric.
Choose a higher setting for the blue, green
and red thread tensions.
The needle threads (blue, green and red)
are too tight and the fabric is puckering.
Set a lower value for the blue, green and
red thread tensions.
