Any ideas, i want to do it tonight so i really can't be buying things. Any suggestions?
Answers:    I'm a minamalist...i close to things simple. Put everything you don't use on a daily idea away in a reachable place. Clear adjectives surfaces, clean everything. Placing a single knick knack, picture or candle on a verbs surface, makes it a focal point allowing the room to pop and not look cluttlered. Also if you enjoy a mirror on a bureau place it opposite a pane or a doorway, it makes the room look bigger.
Not sure what you miserable buy this?
