What causes a sewing machine not to stitch?
If the top thread is not reaching the bobbin, the threads will not lock properly, resulting in a skipped stitch. Re-thread your machine, both top and bobbin threads, and test. If your machine is still skipping stitches, there may be an issue with the timing, which will require expert repairs.
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.
