The Invisible Zipper Foot is very different from a standard zipper foot. It has 2 grooves at the bottom of the foot which hold the zipper coils in place while you stitch. This creates even stitches that are very close to the zipper coil resulting in a flat finish with invisible fastening. The invisible zipper foot makes the process of sewing an invisible zipper MUCH easier and faster. It’s even easier to insert an invisible zipper than setting in a regular zipper! Use the invisible zipper foot to insert an invisible zipper in a dress, a skirt, or even a décor pillow. This foot will save you time and energy and you’ll get great results! NOTE: You can only use this foot with an invisible zipper. This Presser Foot is also included in our top-of-the-line 32 pcs Presser Foot Set.

Instructions & More You can only use this foot with an invisible zipper. An invisible zipper is a zipper with very fine teeth that are not visible from the front– the zipper teeth are visible from the back of the zipper, but not from the top. So, when installed correctly, the zipper is completely concealed. For detailed instructions, visit our: Invisible Zipper Foot Online Manual.
