I just signed up for the Sketchbook Project for the first time this year. I'm really excited and I'll share some of my pages with you once I get my book.
Here's how it works: First pick a theme on their website. You can follow the theme pretty loosely (I picked Monochromatic). For $25, they send you a sketchbook. Fill your sketchbook with your doodles. Then send it back in. It'll travel around to different art galleries where people can look at your book. For an extra $20 you can have it digitized and put on their website for anyone to see. I chose this option. I want to be able to show anyone after my sketchbook is already gone.
Sign up quickly because books need to be in by about mid-January! Go to their website by clicking Sketchbook Project.
