I have interchangeable needle plates for my machine. If you can, put on your "single" hole needle plate. The "zigzag" plate's hole to just too large. Just remember which plate is on when you need to use your decorative stitches or you will break a needle and possibly damage your plate.
Another thing. Try using a fine needle, perhaps a 10 or 12. Fat needles do not pierce the fabric as well as the skinny ones.
