Start with an 8 1/2-by-5 1/2-inch piece of heavy paper. Lay the paper flat with the short side toward you; fold in half vertically. Fold both upper corners down to meet at center crease. Fold sides in toward center so that angled edges line up with the crease. Fold sides in toward the center again, lining up with crease. Type up your wedding information, and have lettering made into a rubber stamp at an office-supply store. Stamp details onto the wing of the folded paper airplane.
