Of every online collage tool we've tried (yes, there've been a few), Moomah is our hands-down favorite. It's super-easy to use and lets us do something childlike without feeling ... well, creepy. The collage options are chic and nostalgic, and we're pretty proud of the final product. Try it yourself, and send a copy of the finished effort to editors@lemondrop.com. We'll post our faves in an upcoming Happy Pill.
