Address + Ticket

OK, you may know about this already because of all the questions I asked about it already, but I am sending my friend a Hogwarts acceptance letter for her birthday. I think she would love it and I really want to make her believe that she is truly being accepted into Hogwarts.
And so you know how on the envelope it says the address of the person?? Well, I don't want to type that up & print it out because then my friend would notice that it had been printed and wouldn't believe the letter was really from Hogwarts. So what should I do? Another thing about the address- what font do you think I should use for the address, if i DO have to type it up?
One last thing- you know in the acceptance letter it gives you the ticket for Platform 9 and 3/4?? Well, I don't know how the ticket looks so if there is a link or something you can give me that shows what the ticket looked like (like it had a picture of the ticket or something) can you give me that link? Or if you can't find a link, please just tell me what you think the ticket says. Props available
