Sewing buttons on by machine is a lot faster! The BERNINA Button Sew-On Foot #18 makes it a breeze to sew buttons, press studs, snap fasteners, hooks and eyes. It features an anti-slide sole that stops the button moving while sewing, while the adjustable pin mounted to the front of the foot will automatically create a thread shank. The length of the thread shank is adjustable for a wide variety of applications, from blouses and shirts, to heavy coats. The pin can also be removed if a thread shank is not needed (such as hooks and eyes).
