These ELAN two-hole sew-through buttons are a versatile choice for shirts, blouses, childrens wear, and craft projects that need a flat, easy-to-stitch closure. The card includes three 18 mm (3/4 in) buttons, giving enough pieces to complete a front or to keep spares for repairs and alterations. Sew through both holes with matching thread, keep stitches even for a smooth lay, and check the buttonhole length before attaching.
