Trying to designate a specific play area in our family room was my goal. It's a large room, however it is being taken over by the kids... not always a bad thing, but it's a space for Mom & Dad, too. Now they have a place to put their books, toys, games, etc. on hand-me-down (but perfect) shelves. We found the table at Pottery Barn Kids and the chairs online.
I made their wall art from canvas, paper, craft letters, and paint.
