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. It will also help prevent skipped stitches and broken needles on thick seams. Great to have on hand whenever you are sewing a project that has multiple layers of heavy-duty fabric! Fits all machines.
