Balmy, breezy weather is the hope of every bride planning an outdoor wedding. But breezes can be the bane of featherlight escort cards lined up unprotected on a table. To make sure the winds don't get the best of them, secure the cards with lengths of decorative ribbon. Starting at the left side of the table, lay 1 1/2-inch-wide organdy ribbon vertically across the tablecloth. Pull it taut, pin in place, and sew the ribbon to the tablecloth at the points where the cloth meets the front and back edges of the tabletop. Let the remainder of the ribbon flow almost to the floor on both sides in the back and the front; repeat until you have created the number of rows you will need for all the cards. Next, starting from the left side, slip the escort cards between the ribbon and the tablecloth, arranging them alphabetically. Note that you must use sheer ribbon so that the names of your guests show through.
