Did this exercise last night. It is about variations in shape and it was very interesting to see it evolve. No matter where you look at the shapes lead your eyes back to the center. No way to focus an outer area longer, cause the eye always wanders back. I love that. The exercises from this book seem to be very simple, but I really learned a lot so far. And I learn how the paint reacts and how the brushes work. I knew I would love painting with acrylics, but I love it even more with every little exercise I make. I hope I can translate some of it into fabric work.
