ELAN 2-hole sew-through button is designed for secure closures on woven or knit garments, repairs, and general craft sewing. This card includes 3 buttons measuring 18 mm (3/4 in), a practical size for replacing buttons on shirts, blouses, cardigans, and jackets without changing the buttonhole. Sew by hand or machine with strong thread, reinforce at stress points with a backing button on heavier fabrics, and test placement before stitching to keep the front placket aligned.
