An idea for hanging artwork

Teaching 600+ artists is a lot of paper. In trying to conserve, I think this may be my solution. My new school is missing sprinklers, so we have to limit the amount of paper per wall ratio. 

The laminated black paper will stay on the wall to frame the ever changeable artwork per every month. 

Thoughts? Or any better ideas?  I enjoy framing the art when hanging but not the use of the amount of paper per week.
