Correct Thread Tension
Lower looper thread and upper looper thread should be well
balanced with the same tension (both looper threads should cross
at the edge of the fabrics). Needle threads should not be too
loose or too tight, but equally balanced tension.

top side of the fabric. Loosen the thread tension of the upper
looper or tighten the thread tension of the lower looper.

right side of the fabric. Tighten the thread tension of the lower
