Fashion a card to look like a dapper shirt cuff, and then use it to present a gift of cuff links (make a set out of shank buttons, or buy new or vintage links).
Cut a 3 1/4-by-9-inch rectangle from construction paper, then round 2 corners. Rubber-stamp greeting on 1 side. Gently bend paper in half. Cut 4 slits for cuff links. To make cuff links, hook 24-gauge wire onto a button's shank; secure with needlenose pliers. Cut wire to 1/2 inch; loop through a second button's shank. Repeat.
