Balanced tension
The needle thread sews a straight seam on the
surface of the fabric, and the looper thread forms
loops on the back.
Needle thread is too loose.
Turn the needle thread tension dial to a higher
number to increase the tension, or turn the looper
thread tension dial to a lower number to decrease the
tension.
Needle thread is too tight.
Turn the needle thread tension dial to a lower number
to decrease the tension, or turn the looper thread
tension dial to a higher number to increase the
tension.
