I'm playing with Notan's today while waiting on the laundry to finish its cycles, using a Sharpie black marker and computer paper. These are just the first of several I plan to do. This is of an iris that we will be painting in the April Paint Along at Painting Friends. I took the reference photo we are using and wanted to learn more about not only the lights and darks but what would make an interesting design/composition. I will be playing with removing blades or changing direction and/or shapes. While doing these I am also trying to keep in mind the Principles and Elements of Composition, so as I mentioned, there will eventually be several little sketches. This is part of the fun of learning to paint.
