Zipper foot #54 with non-stick sole is especially suited to attaching zippers to "sticky" fabrics such as leather or plastic.
Just like Zipper foot #14 /14D, Zipper Foot with Non-Stick Sole #54 features an Adjustable Guide on the top of the foot. This lets you sew perfectly even, parallel straight-stitched seams when edgestitching or attaching piping.
