If you have a designated playroom for your kids, would you rather do a chalkboard or a whiteboard (big on the wall?) I'm going back and forth. Whiteboard for the cleanliness but chalkboard is easier to maintain (no dealing with markers getting dried out, on the carpet, ect.) but the chalkboard is all over the place. we have a small one and I hate the dust. So what do you think, which one?
