this is how many sketchbooks I have going right now. The top one is almost filled, the red one is one of those Japanese ones I think, that open up forever.. Doesn't have much in it yet. The next is my new moleskine I got today. And the last is a large one I got recently too so I can have large drawing paper.
I love buying sketchbooks.. won't buy a new one till these are all filled up though! :)
