I'm doing something else different now, too.
When I am having trouble finding an image to paint, I turn and take a look at my older paintings. Sometimes I want to revisit a particular scene, sometimes an older painting spurs me to try something very different.
One of these (actually several of these) are from old and very old family photos (you'll know who you are!).
