Get Ready, Get Set, Sketch!

There are some fantastic sites that focus on sketching and on sketchbooks. One of these is SketchCrawl which celebrates sketching with drawing marathons from around the world
On 01.22.11, they will be celebrating their 30th Sketch Crawl, and this is all you need: Materials. If you are looking for inspiration on creating your own sketchbooks, check out this neat site (Thank you, @craigr on Twitter!)
Take a look at the SketchCrawl Flickr site for further inspiration!
