Why does my bobbin thread keep getting caught?
This can be caused if the top thread tension is too tight, or if the bobbin thread is not in the bobbin case tension. Make sure the bobbin is correctly seated in the bobbin case (bobbin holder), and check that the upper thread tension is not set too tightly.
How do I stop my bobbin from jamming?
- There are several reasons why your thread is jamming in the bobbin case area.
- Make sure upper thread or needle thread is threaded correctly.
- Make sure your bobbin thread is wound evenly on the bobbin.
- Make sure you are using the correct size bobbin 11.5 mm in height or 7/16 inch in height.
Why does my bottom thread keep bunching?
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 you adjust the bobbin tension on a Singer sewing machine?

If the upper thread is breaking, it could be that the thread path is obstructed, the machine is not correctly threaded or the upper thread tension is set to tightly. Be sure that the machine is correctly threaded and there are not obstructions (for example, thread getting caught behind the spool cap or a “rough spot” on the spool itself).

Why are my bobbins not working on my sewing machine?
Don’t overfill bobbins or they will not move freely in the bobbin case.

The thread that is wound too loosely can cause machine jamming.
