This ELAN button card is made for sewing, mending, and finishing apparel, bags, and handmade accessories for everyday use. It includes 2 button(s) measuring 15 mm (9/16 in) across, sized to coordinate with common buttonholes on shirts, sweaters, and light jackets. Stitch them on with matching thread, test placement and fit before final sewing, and secure the back side well so the closure holds up through wear and routine laundering.
