I have recently started a sketchbook collection on Flickr. I have started scanning a bunch of sketches that currently live in one of my many sketchbooks but also plan to add new material periodically. The thing that I love about sketching is that it appeals to my desire for instant creative gratification.. I can create something with my pencil and a piece of paper in an instant. It is a nice contrast to the more intensive projects that take hours and hours to create. Enjoy the randomness!
