How do you fix an uneven bobbin?

If your bobbin does not wind quickly and smoothly when you press on your foot pedal, your bobbin winder might not be fully engaged. This can cause uneven winding. Make sure you push your bobbin pin all the way over or loosen your bobbin wheel completely to engage your bobbin winding mechanism.

How do I make my bobbin wind evenly?

Place the bobbin, with the holes on the top, on the bobbin winder. Put your selected thread onto the spool pin. Loop the thread around the thread guide, then pull the thread from the inside into the small hole in the top of the bobbin. Wind a bit of thread around the bobbin manually.

Why is my bottom bobbin 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. … In this case, it might be necessary to loosen both the bobbin tension AND the top tension.

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.
