I really wish I could use one sketchbook at a time. I have about 15 multi-purpose books on the go, for to-do lists, telephone numbers, thoughts and sketches. Which makes keeping track a bit tricky..and then there's my hard drive. Errrr.
Here's someone who's got a notebook/sketchbook thing too. http://www.flickr.com/photos/33237593@N06/7922779212/in/photostream/
I feel a notebook shopping trip to Portugal coming on. I wish.
Foxy pattern for imaginary notebook instead.
