Effortless setup for faster workflows: Slides under your presser foot in seconds, correcting foot tilt with no shank adapter required. One of the most trusted sewing gadgets for improving accuracy and saving time on complex seams.

Universal fit for most brands: Compatible with Brother, Janome, Singer, Kenmore, and Husqvarna Viking. This versatile piece belongs in every set of sewing foot attachments, ideal for garments, quilting, accessories, and crafting.

Place the hump jumper under the presser foot at the point where fabric thickness changes, such as hems, zippers, seams, or layered areas.

Choose the 1/8 inch or 3/16 inch end depending on the height difference you need to level the foot.

Sew slowly as the foot transitions over the thicker section, keeping fabric aligned for even stitching.

Remove the tool once the foot is level again and continue sewing as normal. Test on scrap fabric first when using it on a new project.
