Classic 2-hole sew-throughs for everyday garments, repairs and craft projects. The smooth, durable faces stitch cleanly and lie flat for a neat finish on shirts, knitwear and bags. Edges are rounded for easy handling and reliable feeding under the presser foot. Select the 23 mm (7/8in) size to match existing buttonholes and fabric weight. Each card includes 2 button(s). Test on fabric scraps to confirm needle choice, stitch length and tension.
