Super Cheap Dry Erase "Boards"

I saw this idea a while ago somewhere on the internet.  I've been wanting to try it for some time now. I don't know about you but all of my dry erase boards seem to be in really bad condition, don't wipe easily, marker stains and so on.

I am a HAPPY teacher!  I spent 6 dollars and have 24 dry erase "boards!!"
