that sounds like so much fun. please post pics of the finished product! I think you ideas are going in the right direction.
bright colors (pinks, purples,golds,blues,oranges, etc) and I think cherry wood furniture would be perfect to.
lots of pillows on the bed, all different shapes,sizes and colors. a canopy would be nice to.
hmm,what else? whats the size of your room like? what do you do in there? study,watch TV etc? function is just as important as the design itself.
