2. Posters

If you belong to a certain «fandom» or are simply in love with a certain band, posters of your favorite movies and musicians can be a great way to change your bedroom as you grow older. Your room is your space to express yourself, and posters are a great, space-conscious way to do that. You can literally cover your walls with posters to go for that classic, overly-zealous teenage vibe, or just have a few as accent pieces to remind you that you’re part of a really awesome fandom!
