The Brooklyn Art Library in New York City has a program that I'm proud to say I will be a part of this year: The Sketchbook Project. As part of the project, anyone can purchase a sketchbook from the library and fill it almost any way they desire. The participant then mails the sketchbook back to the library, and the sketchbook becomes part of their permanent collection, travels across the country to art exhibits, and will be catalogued and rotated for viewing at the Brooklyn Art Library as long as it stands.
I have filled my book with patterns and textures. Now for the fun part...
