Many schools require their shelves or boards to be covered, and many teachers use bulletin board paper to do this. I would like to suggest that we save paper and consider using old clean bed sheets to cover shelves and the like. If you do not have any old worn bed sheets, ask for some in your weekly parent or school memo. In the fall, you can wash the sheets and store them for the next year. It has worked well in our school and we saved costly paper!
