ELAN two-hole buttons offer a low-profile closure for shirts, cardigans, childrenswear, and everyday repairs. This card includes 2 sew-through buttons in 20 mm (about 3/4 in) that stitch on quickly by hand or with a button-sew program for even results while keeping the surface smooth and comfortable. Match the diameter to your buttonholes, balance stitch tension on a scrap, and choose thread that suits your fabric before laundering or dry cleaning.
