First thing, try a brand new needle.

Then after that, it's an elimination game...changing needle, thread, tension, etc.

What to Do If Your Sewing Machine Is Skipping Stitches

Install a brand new needle and confirm it is inserted with the flat side facing the proper direction.. A bent, damaged needle will sometimes cause skipped stitches or even needle strikes inside the machine. A new needle is the least expensive cure for a lot of sewing machine problems. The needle should be changed about every 8 hours of sewing or at least when starting a new project.

Remove the top thread. ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.

Sometimes, skipped stitches will occur if the needle, thread, and fabric are incompatible. Be sure to use the correct needle for your project. Use a good quality thread--AVOID old or bargain bin thread!

If the machine continues to skip stitches, then it may be out of time. Search for sewing machine timing or take it for service.

Change the needle first and make sure it is inserted correctly. Use good thread i.e.: Guterman or Metler are some. If you are using a stretch material then put a stretch needle in the machine. If you do all this and it still skips then you may have a mechanical problem with the machine. The machine is "out of timing". Have a good tech. look at it. This happens quite frequently on "inexpensive" machines. Sorry.
