Answers:    You could achieve pictures of all your family and friends or something and put a collage of them up! I did that and evryone comes into my room and say,"Wow your room looks really nice!" or you could get an aweosme, colourful picture of something and stick it up in the crucial part of your room that's what my freind did and her room is completely white and it looks really good!! Good luc! :]
