Shank-back buttons sized for coats, cardigans and structured garments. The raised shank protects thread and keeps the button above thicker fabrics for a smooth drape. Clean edges aid handling and deliver a professional finish on jackets, knitwear and handbags. Choose the 20 mm (3/4in) size to match buttonholes and seam details. Each card includes 2 button(s). Test placement on fabric scraps and reinforce with interfacing if needed. Suitable for home sewing, alterations and classroom use.
