Why does my bottom bobbin keep getting jammed?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
Why is my bobbin thread bunching up 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 does my bobbin thread keep tangling in my sewing machine?
Improper Threading If your sewing machine thread is not properly threaded, the bobbin thread won’t be pulled up into the fabric the way it needs to be. Occasionally the upper thread can catch on a moving part or get stuck, which impedes the easy flow of thread through the needle, creating a tangle.

Why is my thread nesting underneath?
Bird nests occur when thread bunches up underneath the needle plate, causing broken threads, skipped stitches, and uneven tension. This is typically caused by the tension balance being out of whack or the top thread is not threaded correctly.
Why does my thread keep Birdnesting?
A tight bobbin tension, together with highly loose needle thread tension, can cause birdnesting. Flagging occurs when the hoop bounces up and down during sewing. If the fabric is hooped too loosely, the fabric can slip or expand in the hoop.

How To Avoid Thread Nests While Sewing
- Rethread. Remove the thread spool and bobbin; rethread your sewing machine with the presser foot up.
- Replace Needle. A damaged or dull needle may be the problem.
- Testing 1, 2, 3. Use threads of different colors in the needle and bobbin to stitch a test seam.
