Why does my sewing machine keep knotting underneath?

Dull Needle The sharp point of the needle catches the bobbin thread, which makes a loop. This interaction creates knots, which are the building blocks of sewing machine stitches. If the needle is dull, this process may not work properly, causing a knot to get caught in the bobbin thread area instead of in the fabric.

Why is my bottom thread bunching up?

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 skipping stitches underneath?

The most common cause of a sewing machine skipping stitches is a problem with the sewing machine needle. The needle may be slightly bent, even if you can not see the bend. It may have developed a dull point from use, or it may have a nick in it.

Why do my stitches keep skipping?

Skipped stitches are usually caused by an old or worn needle. With every stitch, there is friction placed on the point of the needle and with repeated action, the needle experiences abrasion. Over time, the needle becomes dull and doesn’t perform well. This results in skipped stitches.
