The needle thread sews a straight seam on the top side and the looper thread forms loops on the under

Stitching direction side of the fabric.

Needle thread is too loose

Turn the needle thread adjusting dial to a higher number. Or turn the looper adjusting dial to a lower number for looser tension.

Needle thread is too tight

Turn the needle thread adjusting dial to a lower number. Or turn the looper adjusting dial to a higher number for tighter tension.
