After creating black and white patterns with tape, I wasn't sure what to do next with this painting. But something made me want to "write" with black on white and white on black, so that's exactly what I did.
I fell in love with this painting just the way it was, but after a day or two I came to my senses and continued to work on it. First, I'd have to destroy what was already there. I did this by applying a thin white paint loosely with a brush, letting it play out where it would in a drippy, carefree manner.
Then I drew more lines with black into the white paint to attempt a bit more structure and control:
Now it is nicely messed up so I can keep working on it.
