Genuine Akoya shell buttons cut from nacre for a luminous, iridescent finish. They lend a polished look to knitwear and garments; subtle colour and grain variations are inherent to this natural material. This card includes 4 buttons sized 23 mm (7/8 in). The flat 2-hole style sits neatly against fabric and is easy to sew by hand or machine. Ideal for garments, knitwear, bags and craft projects; choose needle and thread to match fabric weight.
