We went with vintage airplanes and vintage sports themes in my sons rooms. The "cutesy" trucks and planes themes don't "grow" with your child, so I selected themes that would still be "cool" when they were teenagers!
First, I selected a border paper that I liked. Then I painted the walls a coordinating color (brick red to go with the sports theme, and navy blue to go with the airplane theme). The Company Kids, Sears Kids, JC Penney and Target catalog/website all have some GREAT room/theme ideas!
In the sports room I added: some vintage sports prints, team pennants, a football bean bag, sports ball area rug, sport theme bedding/drapes, wall hooks shaped like sports balls, and a 3-D sports ball lamp.
In the airplane room: I added airplane bedding/drapes, an airplane lamp, framed airplane posters, displayed airplane books on shelves and hung model airplanes from the ceiling!
