A jean-a-ma-jig, also called a “hump jumper,” is a tool used to lift up the presser foot of your sewing machine to help it sew through bulky seams.

  • Helps prevent skipped stitches and broken needles
  • Hem jeans quickly and easily
  • Great to have on hand whenever you are sewing a project that has multiple layers of heavy-duty fabric
  • Fits all machines
