Answers:    Paint colors in stripes and stuff all over the walls. Make a Picasso similar to room with fun shapes and stuff! Have fun doing it. Close your eyes and squirt paint everywhere to see how it looks! Be creative! w00t!
maybe you should try to picture what would look best contained by your room. dont try something you get tired of, because then you'll want to modify it right away and im sure your parents dont want to keep spending money especially in a unusual house HANNAH MONTANNA!!
