I stick funny posters, newspaper cuttings, photos, my own home-made posters, random printed out things, world maps, periodic tables, London Underground maps, medication box inserts (the ones that tell you the information about them), chemical structures and even USB cables on my walls.
This is to ensure that my walls are almost completely covered with things. I cannot stand bare walls.
When I move out of supported housing I am putting light blue wallpaper up in my new house (I'm going to move in with a friend) and drawing all over it.
