My work on this 30 paintings-in-30 days was all created on birch. And, it wasn't until getting literally almost to the end of the challenge that I decided to follow the birch for ideas. It was almost as if the real collage segments were the markings of the tree itself. But, after adding the actual collage in this painting ... I fell for the soft colors and the sense of space. Then I followed the rhythm of the panel and I depended on the bold graphic charge to give this painting momentum.
