I've always loved the tactile part of fabric. I'm always thinking outside the box and "what if", which I consider an artist. When I'm playing/working (plorking), I'm focused and can't/don't multi-task, that includes communicating with other people. My first approach to a project is to reach the goal (type A?). I've learned to enjoy the process and am much happier. And I'm expanding my communication with friends.
So I guess it's a form of expressing myself, touchy/feely, therapeutic, and making friends.
