I discovered last year this incredibly cool project from The Art House Co-op but didn't have the time to participate. This year, however, I should have plenty, and I'm very excited for my book to arrive. It's a really neat project, basically a library of sketchbooks that tours different cities, and people can check them out just like regular books. I choose "A Grey Life' for my theme because I like grey ad thought the theme would push me a little more than simply choosing 'Monochromatic.' I like the option to have them digitized the site provides, but I'm too broke and not vain enough to go for it. Maybe next year!
