Buttonhole Foot #3 is ideally suited to sewing buttonholes, as well as gathering with cord or elastic (smocking). Thanks to its practical grooves, Buttonhole Foot #3 is able to glide smoothly over the thread beads of the buttonhole, enabling particularly easy and precise sewing. This foot allows you to be fully in control of the length of your buttonhole by using manual mode in your 5.5mm or 9mm Bernina machine.
