I've got into a routine of painting every evening at the kitchen table. Though I have a few ideas of what I might paint in the future, I never make the final decision until I am actually sitting down and ready to paint. In that way the exercise feels oddly childlike...in that I do no preparation, and I am painting in the moment, just for the joy of it.
Perhaps some of that attitude will flow into the way I feel when I sit down to design fabric. I love the sense of play I am feeling when I do these paintings...an attitude of "what the heck I'll just try it and see what happens".
