Classic 2-hole sew-through buttons sized for everyday garment repairs and new makes. The 11 mm (3/8″) diameter works for shirts, knitwear and light outerwear. Each card includes 4 buttons for coordinating closures or spares. Smooth, chamfered holes accept hand or machine stitching for a secure attachment. Use to refresh garment fronts, finish handmade pieces or add accents on bags and home décor. Measure buttonholes to confirm fit and test thread and needle on a scrap to prevent puckering.
