Want to make a white board?

Michelle at Delightful Learning shows how she did it.

I saw another interesting possibility when I was in a teacher's supply store: you can get flexible, adhesive whiteboard material in sheets or on rolls like wallpaper. I don't know how durable it is, but it might work if you have limited space and, say, want to turn the side of a cupboard into a whiteboard without nailing anything up.
