ELAN shank buttons are carded sewing notions for repairs and for finishing garments, knitwear, accessories, and home projects that need dependable closures. This card includes 3 buttons in 12 mm (1/2 in) diameter with a shank-back build suited to everyday clothing, costumes, and craft use. Choose a needle and thread that match your fabric weight, then test spacing and buttonhole fit before final stitching for smooth fastening and a neat finish.
