Best answer: What causes the thread to bunch up when sewing?

How do I stop my thread from bunching up when sewing?

Hold the thread in both hands with light tension. The thread is positioned in the pretensioner. Also make sure the thread is positioned properly between the tension discs on the top of the machine: If it is not positioned correctly, it will not have any tension, and will be pulled under with the very first stitch.

Why does my thread keep bunching up underneath?

Your Thread Tension Is Too Tight

Sewing machine manufacturers suggest that you don’t mess with your bobbin thread tension too much, but you should adjust your upper thread tension if you keep getting bunched up thread underneath your fabric. If your tension is too tight, it can pull your thread and break it.

How do you fix bobbin tension?

Bobbin tension or bottom tension is fixed by adjusting a small screw next to your bobbin case’s thread opening.To adjust, use a tiny screwdriver and turn the tiny screw to the right for tighter tension or the left to loosen bobbin tension.

What width should my sewing machine be on?

A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.

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.
