Thread the machine, thread the needle, and pull a couple of feet of thread through the entire path of the machine. Check for hitches in the thread path and make sure the tension is on the loose side. Next, single stitch to tie off, and then, at a slow speed, stitch a straight line. Place a scrap of fabric in the margin of the backing beside the top for this. How does it look from the top? Feel the underside and run a fingernail along the stitch line. If there's a "pop pop pop," the top tension is too loose. Tighten the top tension a little at a time until you see just a pin dot of the bobbin thread on the top side, then back it off 1 or 2 clicks. Then stitch circles, both clockwise and counterclockwise, inspect both sides, and fine-tune for the best tension.
