Buttonhole Foot #3C is designed for versatility, making it perfect not only for sewing buttonholes but also for gathering with cord or elastic, such as in smocking. Its practical grooves allow the foot to glide effortlessly over the thread beads of the buttonhole, facilitating smooth and precise sewing. Additionally, the design includes a convenient slot that enables you to pull the upper thread to the back before you start sewing. This feature allows for the creation of attractive buttonholes, whether you choose to include cording or not, and ensures that you can easily achieve your desired length with each buttonhole you sew.
