So I did this page last night. The directions on the page say to "wrap something with this page", so I cut the bottom off, and folded it into an envelope. On the front I wrote Harry Potter's address: (Mr. Potter, The Cupboard under the Stairs, 4. Privet Drive, Little Whinging. Surrey) In the back I sealed it with "the Hogwarts seal". You can actually open the envelope and inside is a letter. (from Albus Dubledore of course!!!) The letter is being delivered, by Harry's owl, Hedwig.
