We're in the process of moving and my 4-year-old daughter's friends from preschool are all talking about writing letters and sending pictures they've colored to each other (they are so sweet and we are so sad to leave them). I was just thinking because of that "what happened to getting anything FUN in the mail?" All I get is bills and advertisements. So although I'm frankly nervous that my offering of happy mail may not be as awesome as some of yours, I'd love to give it a try. It would be a fun project that my daughter would get into too
