ELAN shank buttons provide a raised attachment point that is useful for thicker fabrics, costumes, and decorative closures where you want stitches kept out of sight. This card includes 2 buttons measuring 23 mm (7/8 in) in diameter, and the back shank creates space for plackets, trims, and layered seams. Stitch firmly through the shank with doubled thread, secure knots well, and consider a backing button on delicate fabric to spread the strain.
