When my client asked me to decorate her twin boys' rooms, I knew I wanted them to be complimentary, but different, just like the boys. We chose color schemes for each of them, and then went to work selecting furniture, rugs, bedding, lighting and accessories to make each one unique. We decided to add interest to the walls by painting the bottom half a dark hue and leaving the top half white. We then chose a contrasting color for the curtains, whose vertical length breaks up the horizontal line just perfectly.
