I'm not really super into the idea of favors, but I saw on Shutterfly that you can make personalized decks of playing cards.
FH is a magician (as is the Best Man and several of our guests), and carries decks of cards with him everywhere to do magic for people. I'm thinking it might be cute to give out personalized decks of cards as favors.
Would this be a good favor, or would you likely not bring the cards home with you?
