Some out-of-the-wedding-book mementos require planning, but I'd say the best ones are spontaneous, like the couple who kept a Spider-Man water squirter that was a prize from a box of Froot Loops guests opened to use as confetti in a makeshift, postceremony parade. One bride went all Sisterhood of the Traveling Pants for her destination wedding by sending her wedding-day shoes to all her female friends who couldn't make it for signatures.
And then there are the unexpected mementos that start traditions. One couple kept a jar of rain from their wedding day, which they've since used sparingly to baptize their children. A little water remains, but the woman has begun collecting rain for other couples with stormy-day weddings. Sunny-dayers, you're on your own!
So planned or not, if you're married did you keep anything out of the ordinary? And if you aren't, would you plan to?
