Why is my bottom stitch not straight?

The most common reason for uneven stitches is old or inferior thread. Another cause for uneven stitches is the fabric is being pulled while sewing. When sewing it is important to remember to never pull the fabric – allow the fabric to be taken up by the sewing machine.

Why is the bottom stitch on my sewing machine loose?

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 is my bottom stitch not working?

First, check that your needle is installed correctly, not bent or otherwise damaged, and that you’re using the right type of needle for your project. If the top thread is not reaching the bobbin, the threads will not lock properly, resulting in a skipped stitch.

Why is the tension wrong on my sewing machine?

Needles, threads, and fabrics: Different thread sizes and types on top and in the bobbin can throw off basic tension settings. A needle that’s too large or small for the thread can also unbalance your stitches, because the size of the hole adds to or reduces the total top tension.
