I just entered a contest, illustrating a letter from Santa to a child. If you go here: Free Letters from Santa - Send a free letter and vote for me! You can e-mail or print out a free letter from Santa Claus to your child. Once you finish, it gives you the option to vote for a new design. Mine is the one that has a blue border with white snowflakes and a cartoon Santa at the bottom.
If you print out the letter to your child and would like it to be postmarked from the North Pole put your letter in an envelope addressed and stamped to your child in another envelope and mail it to this address:
North Pole Christmas Cancellation,
5400 Mail Trail
Fairbanks, AK 99709-9999
