Well, I did manage to finally get a new underpainting going. It took me all day to settle down and get to it, but I finally did. And as always, I enjoyed it so much that I have been berating myself for not working more on these. It's so hard for me to get started on each one. They are just really intimidating, I think.
I should probably put a big post it note on my studio wall (or maybe on the computer, that might be the real culprit here) that says "You will LOVE the process of making the underpainting, so JUST DO IT!
