Chalkboard wall. Pinner Said: "I have two of these and they have been in my home for ten years! The kids LOVED LOVED LOVED it. The one in the kitchen was for family notes. The one in their play area is huge. And chalk is easily removed from other things (like carpet and walls)."
A chalk board on a back wall! Would be perfect to write down messages,instead of using post it notes everywhere, and a great thing for kids to draw on instead of marking your walls.
