Button Napkin Rings
Source: Martha Stewart Living, February 2006
Call on loose or mismatched buttons to serve as the charming clasps on handmade napkin rings. You'll need shank buttons, which have holes on the back. We used a variety of mother-of-pearl buttons, each about 1 1/2 inches across. Thread a 12-inch length of cording through each shank, and tie its ends in a knot. Secure knot to shank with a needle and thread so that it will stay hidden behind the button. Wrap cording around a folded napkin, looping it back over the button to secure.
