Classroom Poster Storage

I got really tired of having my posters curl up in that all too familiar green and purple box. 

Besides posters curling, the box would get bent and crushed so easily. 

I had a divine revelation about how to store my posters. All you need is, some wall space or space on the side of a cabinet, a hole punch, a few binder ring clips, and a few 3M hooks. 

I have my posters organized by subject, and I have anywhere between 5-15 posters in a set. 

The 2lb 3M hooks hold up nicely (I hope)

The finished product. It takes up essentially no space at all, I can see all my posters, and they stay flat. I'm hoping it will be very useful this school year!
