Why does my sewing machine skip stitches?
The first thing to check when your machine starts skipping stitches is the needle. If you haven’t replaced it in a while, do it now. Be sure that the needle shank is inserted all the way into the needle bar and follow the directions in your owner’s manual for proper installation.
It’s possible that you have the wrong type of needle for the sewing that you’re doing. For example, if you’re working on knits, change to a stretch needle with a more rounded point to avoid damaging the knit fibers. If you’re topstitching, you’ll need a needle with a larger eye to accommodate the heavier thread. For more information on selecting the right needle, see SEW-lutions Guideline 22.115 Sewing Machine Needle Chart.
Fabric that isn’t preshrunk can also cause some stitching difficulties. Residual finishes can cause skipped stitches, so always preshrink before sewing.
Incorrect machine threading can be another culprit–be sure the bobbin is inserted properly.
Be sure your sewing machine is clean and lint-free. Follow the instruction manual to clean and lubricate the machine, if needed. If all else fails, talk with your sewing machine service person about the skipped stitches, as it can be a timing problem.
