The Sensor one-step Buttonhole Foot measures as it sews, making every buttonhole the same size. The button size is adjusted in 2 mm steps.  Snap on the Sensor One-Step Buttonhole Foot. Plug the cord into the socket near the light on the machine. Line up the white range on the side of the wheel with the white marking line on the foot.  Set the button size on your Husqvarna Viking sewing machine.  Lower the presser foot and sew.
