A dull, bent or wrong needle is the number one cause of skipped stitches in embroidery. It's the quickest thing to check and fix, so always start here.

• Replace the needle with a fresh embroidery needle - not a standard sewing needle
• Make sure it's fully inserted with the flat side to the back and tightened securely
• Change needles every 8-10 hours of embroidery or when switching to a new fabric type

Incorrect threading is the second most common cause. Even if you've already done it, go through the full process again slowly and carefully, referring to your manual rather than going from memory.

• Raise the presser foot before re-threading so the tension discs open properly
• Follow your machine's threading path step by step, making sure the thread passes through every guide in the correct order
• Re-thread the bobbin too and check it's inserted correctly

Poor quality or old thread can cause skipped stitches as well as breaking.

• Make sure you're using good quality embroidery thread - not standard sewing thread
• Check the thread is flowing freely from the spool with no catching or snagging on the way to the machine
• Check the spool cap is the correct size for your thread

Tension that's too tight or too loose can both cause skipped stitches - the thread loop needs to form correctly for each stitch to lock.

• Start from your machine's default tension setting
• Adjust gradually in small increments, testing on scrap fabric after each change

Loose hooping is a very common cause of skipped stitches in embroidery. Any movement in the fabric as the needle comes down can cause it to miss forming a stitch.

• Check the fabric feels taut in the hoop with no give or movement
• Re-hoop carefully if there's any slack - the fabric should feel like a drum
• Make sure the hoop is attached firmly to the machine and isn't shifting during the design

Insufficient stabiliser means the fabric can shift slightly under the needle, which is enough to cause skipped stitches.

• Make sure you're using the right stabiliser type for your fabric
• Check the weight is appropriate for the density of the design - a dense design needs more support
• If in doubt, add an extra layer and test on scrap before returning to your project

Running the machine too fast, particularly on dense designs or difficult fabrics, can cause the machine to skip stitches.

• Slow the machine down and let it work at a comfortable, steady pace
• This is particularly worth trying with specialty threads like metallics, which need a slower speed to stitch cleanly

Before returning to your project, run the design on a piece of scrap fabric of the same type. Check carefully for any gaps or skipped stitches before committing to your actual piece.
