What do you think of chalkboard walls? Currently, they're all over the design scene. I spot them most in kitchens, kid's rooms, and workspaces. Creating one is as easy as buying a can of chalkboard paint!
I can certainly see myself experimenting with this 'easy to do' idea one day. They're whimsy, creative, practical, and you can write inspirational quotes all over them (that's what I'd do!).
