I'm sorry I didn't read why this was done. Congrats on graduating. And I feel like doing the same thing for my graduation party.........now all I need to do is talk my parents into it which shouldn't be too hard. (we're all potter nerds)
And it doesn't sound cheesy. Every potter fan knows how it feels to be right there with Harry through his adventure
EDIT: Okay before I forget to ask again I was wondering how you did the pins and the books?
