These ELAN shank-back buttons offer a larger raised closure for coats, heavy knitwear, bags, and costume pieces where you want easy fastening over thicker fabric. Each card supplies two 23 mm (7/8 in) buttons, sized for common outerwear buttonholes and for matching replacements on a finished garment. Sew through the rear shank with reinforced stitches, use interfacing behind light fabrics for support, and test the buttonhole fit before stitching permanently.
