My shelf when opened

Now over a year ago I got this idea of creating a shelf that would fit all my medium sized items, like punches and decoupage glue tubes etc... I have an issue with space in my craft room, so I wanted that this shelf would not be wide. As I don't like that my things are behind each other - that usually means just one thing, this shelf should not be deep - just so that I can place a jar of flowers or punch in it. But this also means that I will not be able to put lots of things in this kind of shelf. I started to work on this problem, and I found a solution - page shelf.
So this is my new self-made shelf. Basically these are two very narrow shelves, that I've attached together with hinges and they have wheels at their bottom, so I can move them and open and close lake pages of a book.
