Exits can make fantastic pictures! There's a lot of different options for what you do when you exit from the ceremony, church or reception! I had bubbles (yes that's me and Mike up there), my oldest sister did petals while leaving the church, my other sister passed out bells as they exited late at night. Here's some to get your creative juices flowing;
balloons, bubbles, petals, sparklers, rice, flying lanterns, cut up paper confetti cones, confetti poppers, ring bells, wave ribbon banners, etc..
Any more favorites out there?
