Why is my machine embroidery loose?

Looping is usually caused by thread tensions that are too loose. It could occur either on the top or bottom of the design. Both bobbin and tensioner could be the culprit. Check if the problem is caused by tensioners by turning tensioner knobs to the right to tighten.

Why is my thread bunching underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

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.

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.
