Depending on the model of BERNINA this foot is for sewing automatic buttonholes with or without cording. The sensor can measure the buttonholes automatically based on the size of the desired button. This allows you to produce any number of buttonholes of the exact same length. Use together with the fabric-feeding aid or the buttonhole leveler, if required for bulky fabrics, and the button-sew-on foot to create perfect buttonholes with consummate ease.
The feet and accessories listed here are for recent and current BERNINA Sewing Machines. Not all accessories are available for older machines, so please do not hesitate to ask us about availability of accessories for your particular machine.
