Martha Stewart Weddings, 2000
Try a who-will-marry-next tradition that Turkish brides have been practicing for generations. Before you start down the aisle, have your single bridesmaids (or any female friends or relatives who've yet to marry) autograph the sole of your bridal shoe. After you've danced the night away (and tossed your bouquet), legend has it that the person whose name has faded the most will be the next to marry.
I did this for my wedding. I had my shoes at my shower, and all of my single friends signed the bottom of my shoes, it was such fun, and now I have a great memory of who was still single at my wedding; as just about all are married now. =)
