This EMBASSY sew-on button card is suited to everyday mending and new makes for apparel and accessories. It includes 3 buttons sized 18 mm (3/4 in) for shirts, knitwear, costumes, and sewing projects. Test the fit with your existing buttonholes and stitch firmly so closures stay aligned through laundering and use, keep the card in your notions kit so replacements are easier to match and organize and check stitch tension on a scrap for a tidy finish.
