CREATIVE FAN MAIL IDEAS ?

Usually, if I like a celebrity, I just tweet them & support them. But now, I'm kind of obsessed. I'm usually not the type to send fan mail. But now, I really want to send some. I saw Cody Simpson in concert yesterday. I gave him a note with silly bands & a kangaroo to remind him of home (: He makes me really happy. I just really would like him to know how much I love him & appreciate all of his music & hard work. I don't want this to be any fan mail..I want this to be something he'll remember. I really want to make Cody smile. I need ideas. Help?
