@32redsox: Thought you might already have it, your book looks awesome, does it have other spells too? Unfortunately you can't change your username while your a free member you have to be a premium member for that.
@HarryPotter1234: The size of the Hogwarts Express ticket has been discussed earlier in the thread, no idea where but you'll find it with the search feature at the top of the page.
@HarryPotter 1234 and 32redsox: I'd recommend slowly making your way through all our pages, it'll be worth it. Harry Potter props are a marathon not a sprint, so no great rush, you'll be surprised by what you find hidden in the posts and it'll give you a better idea of how the thread runs etc.
@sonicfreak04: With the few ref images that exist of that cover it's hard to piece together, as to my knowledge no one has seen the back, but myself and Lemonlemonuk have been working on it independently and we're both going to the London tour soon so we'll try to get more ref from there to get it completed.
