How do you adjust thread tension?

Changing Bobbin Tension

Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension. Some quilters keep two bobbin cases on hand, leaving one as-is from the factory and using the other when they need to make adjustments.

How do I know if my bobbin tension is correct?

The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.

How often should you clean and lubricate the sewing machine?
