I have to admit: I have never, ever in my life wanted white walls. So it's a little weird to be completely obsessed with white right now. The Mr. and I currently live in a very brown house; it's all brown floors, brown stairs, brown couch (what? I bought it before we moved!) and white walls seem like the only thing to combat the sea of brown. Not taupe, eggshell, cream, just white white white. I've been pinning and saving any inspiration I can find with white walls. Here are a few favorites below...
