Shank‑back buttons sized for coats, cardigans and structured garments. The raised shank protects thread and lets the button sit above thicker fabrics for a smooth drape. Smooth edges aid handling and provide a professional finish on jackets, knitwear and handbags. Choose the 11 mm (3/8in) size to match buttonholes and seam details. Each card includes 4 button(s). Test placement on fabric scraps and reinforce with interfacing if needed. Suitable for home sewing, alterations and classroom use.
