To recreate "Hogwarts Castle", Bloo and I decided to set up stations for the different subjects at Hogwarts - DADA, Chams, Transfiguration, Care of Magical Creatures, Divination, Astronomy (it was a shame that all the stars fell out) and of course, Potions (which was actually an open bar so people could brew their own Veritaserum or whip up some Amortencia). We actually painstakingly printed labels for the books and re-covered my own books (including Med books!) with felt paper to make the different Hogwarts textbooks (and several others, like the Quidditch books and magical cookbooks). The print-outs of the Quibbler were given as souvenirs, after we'd stuck on the photos of the guests on them.
