Gab Bedrooms
Girls bedroom maybe - 1 pink wall, wall behind bunks. I have another idea they might like we did for Oscar, an instant cubby with a curtain that runs on ceiling around the bed, the curtain can then add the color dimension to the room and runs from floor to ceiling making the ceilings look higher. http://www.theorangenest.com/a-curtain-cubby/
Soothing
white on white, mirrors and detail. This room is small but the large artwork behind the bed is fitting and it all works. a graffic piece of art from your sister might work here, as u walk past the door it would pop every time and be a statement piece for the room
