How to Make Your Room Like Hermione's (Simple Things)

The last part was about large, time consuming things. This part is about simple things you can do in fairly little time, with minimum money spent.
1. Keep your room clean. More details to come.
2. Display every single book you have. Don't hide any in baskets, put them on shelves. A good idea is to alphabetize your books by author, it keeps them organized and easy to find. Put any library books on shelves, but away from books you own so they don't get mixed up.
3. Make sure you have a working clock in your room. It could be a digital alarm, or a small silver analog that sits on your bookshelf. Or it could be both.
4. Keep lotion, hand sanitizer, and lip balm at your disposal. Put them on your nightstand, maybe.
5. There are three wizarding books that have been published: Fantastic Beasts and Where to Find Them, Quidditch Through the Ages, and The Tales of Beedle the Bard. You can probably find them at your library, or you could buy them. I like this set at Amazon. Keep these books on your nightstand, or you could put them with the rest of your books to add a wizarding touch.
6. It's not a must, but you could add select Halloween decorations. I know that right now, they just put them in stores although you can get them online year-round. Add a small cauldron maybe, or a witch's hat. Some Halloween decorations can have Harry Potter-ish effects.
7. If you want to go way above and beyond, get a cat. One that is orangish or has a squashed looking face is preferable, although any cat would do. You could also get a cat they've had for a long time but nobody wanted. That's what Crookshanks is.
8. Hang up your Gryffindor pride! You can find banners for cheap online, or you could put up posters. In the Chamber of Secrets movie, Harry has his Gryffindor tie tacked to the wall. You could even just print out the Gryffindor crest and tape it up in your room. Anything is good.
