Description

Conquer thick seams like a pro! The Jean-a-ma-jig (also known as a Hump Jumper) is the essential tool that eliminates the frustration of sewing over bulky seams and thick layers.

Solves Common Sewing Problems:

  • Prevents Skipped Stitches: Keeps your needle moving smoothly over thick seam intersections
  • Stops Broken Needles: Reduces needle stress when crossing multiple fabric layers
  • Even Stitch Formation: Maintains consistent tension for professional-looking topstitching
  • Universal Fit: Works with all sewing machine brands and models

Perfect For:

  • Hemming jeans and heavy denim
  • Topstitching jackets and outerwear
  • Quilting through multiple layers
  • Upholstery and home décor projects
  • Towel hemming and thick terry cloth
  • Any project with bulky seam intersections

How It Works: Simply place the Jean-a-ma-jig behind your presser foot when approaching a thick seam. It levels your presser foot, allowing smooth fabric feeding and preventing the dreaded "seam hump" that causes stitching problems.

Professional Results Every Time: Transform challenging thick-seam projects from frustrating struggles into smooth, professional finishes. No more re-doing topstitching or dealing with uneven stitches!

Trusted Dritz Quality: Made by Dritz, the professional choice for reliable sewing tools since 1870.
