Lily Gahagan This reminds me a lot of Anthropologie's bedding. I don't see this exact pattern on their site anymore, but here's one with a similar mix of bright colors:
Work in bold, graphic patterns. If your wallpaper can be categorized in the black, white, gray or neutral families, then you’ve got a great opportunity to inject color and a sense of playfulness through bold, colorful prints. It’s a no-brainer for kids’ rooms, where fun is always welcome!
Enhance the graphic appeal. There may be no TV watching in your child’s bedroom, but other than that, decor rules are slim, so get your pattern on. Choose funky, colorful prints and mix them with neutral patterns to create a balanced look that screams delight.
This paper is also a wonderful choice for a child's room. Here it provides a great backdrop for a mix of brightly-colored patterns and a stuffed animal collection.
Build a bridge between rooms. This bedroom was created for a 12-year-old girl. "She loves ecology and her stuffed animals," says designer Michael Fullen. "We combined the wall covering, which is from Cole and Son, with other elements that reflect her interests."He adds, "The home is contemporary, so the crisp black and white wall covering seemed appropriate to bridge the child's desires with the modern decor of the rest of the home."
Cool huh?
