Why is my sewing machine making loops underneath?

Why is my thread looping 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.

Why is my sewing machine loose underneath?

The machine is not correctly threaded

If the machine is threaded wrong, not only does it make the thread breaks easier, but is also more likely to create loose stitches. Check the threading to see if the thread has passed through the entire thread guides, the take-up lever and the eye of the needle.

How do you fix a loop under fabric?

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.
