ELAN sew-through buttons are an easy way to refresh closures on shirts, cardigans, uniforms, and lightweight bags or craft projects. This 2-piece card includes two-hole buttons sized 23 mm (7/8 in) that lie flat, making them quick to stitch by hand or with a machine button-sew setting. Check spacing and alignment before you sew, and use thread suited to your fabric weight to reduce puckering around the buttonhole area.
