I have a spot in my room where the back of a bookshelf is showing. I had thought about getting something like this to stick to the back of it to make a dry erase surface. What I would REALLY like to do is make it magnetic. Is there some kind of peel and stick magnetic type of thing? I have seen a pin on Pinterest with an oil drip pan screwed to the back of the bookcase, but I highly doubt I would be allowed to screw something onto it. Any other ideas? I'm trying to think of a way to make the back of this bookcase useful for word work. It's not a tall bookcase - I should have measured today, but it only has 2 shelves on the inside.
