If the needle hops, skips, or is stuck to the thread, the needle is too small for the yarn you have selected.

Try to move up one needle size and try the test again. If your needle and thread ratio is not proportionate, you run the risk of bunching your thread under or over the fabric.

If you mistakenly hit a pin while you were sewing or maybe struck a needle plate, you may have bent or damaged the needle.
