So, there's this guy, Ivan Cash. He had people send him emails of letters they wanted sent to people, and then he designed the letter, and sent it. He published them in a book, so you can see examples when you click the link. Anyway, from now until Friday, you can email him a letter, and he will make it into a snail-mail letter, and send it...he can add drawings, doodles, etc. It's free to do. You won't really get an idea of what he does, until you check out the website.
I wrote a letter to my unborn child, and emailed it to him. When I get the letter in the mail, I plan on framing it, and hanging it in the nursery. I am sharing the link, because I thought maybe other's would think it was something they wanted to do, as well. In the email, I told him to take creative liberty in adding doodles to it, so I can't wait to see it!
