Writing fan mail and collecting autographs through the mail (TTM) is a great hobby for kids and teens. The hobby gets kids excited to write because they are writing about what interests them most. For example, if a kid likes video games, they can write to the game studio that developed their favorite game. They will love getting a reply back on official letterhead and they may even be lucky enough to get some free swag as well. Be sure to check out the complete guide on writing fan mail to guarantee the greatest chance of success.
