VROOM VROOM. The “tire tracks” on the wall of this little boy’s bedroom? They’re actually a hand- painted stencil. The design, featured in From Classic to Contemporary: Decorating with Cullman and Kravis, uses paint rather than wallpaper, since paint is low-commitment and can be touched up in case of scuffs or an errant scribble. Get a similar, kid-friendly look by incorporating movement and high energy—both in the form of a high- octane color palette of blue, orange, and green, as well through more literal interpretations such as a British- designed roadster toy car and wooden Radio Flyer tricycle. Softening the space is a chevron carpet in a subtle neutral—a cozy base on which to layer an apple green rug. While the animated design works now for a young, active boy, it can easily shift gears as he grows up. “Good design is still about proportion, composition, and a balanced range of colors, materials, and textures that you respond to,” Cullman writes, “no matter your age or personal style.”
