Buttonhole Foot #3 is specifically designed for sewing buttonholes and excels at gathering with cord or elastic, making it ideal for smocking techniques. Its practical grooves allow the foot to glide smoothly over the thread beads of the buttonhole, facilitating easy and precise sewing. Before you start, the upper thread can be conveniently pulled to the back through a slot in the foot, ensuring a tidy setup. This feature enables you to create attractive buttonholes, both with and without cording, in your desired length, providing you with versatility and precision in your sewing projects.
