ELAN shank buttons add an elevated closure for garments and accessories where you want extra thread clearance over thicker layers. This card includes 4 button(s) sized 12 mm (1/2 in) across for coats, sweaters, knitwear, costume work, and replacement fastenings. Confirm buttonhole fit before sewing, and attach through the shank with sturdy thread so the button sits smoothly without pulling the fabric.
