Another artist who employs this method and whose work I've loved for a long time is Stephanie Dotson. She make beautiful "printstallations" out of paper and other materials like felt. I'm absolutely crazy about her pieces and the kind of detail she gets with hand cutting is crazy! Stephanie is featured in the book Illustration Play. This book is definitely worth checking out if you haven't already. There are many great artists here.
If anyone reading this also does a lot of work with the xacto please leave comments telling me how you do it comfortably! My fingertips are a bit tingly and my shoulders hurt. I feel like I must be doing something wrong!
