How I store my sketchbooks (now).

I recently changed the way I store my old sketchbooks. Before this change, I had a large box on top of another large box with some more sketchbooks piled on top of those. But it was impossible to take a look at old sketchbooks. And it was getting harder and harder to add new ones to the pile without ruining the whole structure. 
So I got them all out, decided to keep the oldest 50 or so in the box and the rest are on the shelves - easy to pull and flip through by me or a guest. (Took me two days - mostly because of all the memories I wanted to refresh by looking at my sketches).
