My walls are covered in posters, flags, giant clocks and novelty items...think TGI Friday's (probably a childhood influence kicking in), but in a bedroom. Hey, I've even got a ceiling cat!
I cannot live without my posters. I use them as a source of inspiration for my artistic work. They're part of me and my personality. As I do almost everything in my room (I house-share with my grandparents), I want to feel comfortable - plus posters look kick-ass.
