Why is my sewing machine making loops underneath?

Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. If the loop is on the under side, it is usually best corrected by adjusting the upper tension.

Swiftly pull up on the thread. 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.
