At our wedding we decided to include a sort-of photo booth and encouraged our guests to get their picture taken via Polaroid camera, and write on it in place of having a guest book! My cousin did this at her wedding and we totally copied the idea, and it turned out even better than we could’ve expected. I cherish these so much and have resisted the urge to store each one in an air-tight bag (or in a secret safe that we keep behind a painting?) since the wedding. Plus, just looking through any wedding-related photos always gets me a little misty eyed!
