Why are my sewing machine stitches crooked?

If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. … Don’t be tempted to push the fabric from the front or pull the back of the machine whilst you’re sewing as this will certainly lead to uneven or skipped stitches.

Your Thread Tension Is Too Tight
