To properly install an invisible zipper, you must have an Invisible Zipper Foot. As the zipper coils are guided through the tunnel system, the needle sews as close the coils as possible. This easy-to-use foot ensures your zippers are finished professionally and rival that of any high quality garment. Invisible Zipper Foot #35 is ideal for inserting zippers invisibly into garment seams. In addition, this presser foot is a reliable helper when sewing home furnishings and accessories. Two diagonal grooves act as a guide, making zip insertion a breeze compared to the standard method. Located in the sole of the foot, the grooves easily accommodate the zipper coils, which are fed through at the same time as the zipper tape is guided under the foot and sewn.
