Gouache studies

These little gouache studies were done during January and February. I've been searching for a medium that I feel comfortable using in my car, for those days that one just cannot be outside. We get a lot of those during the winter here. Oils are potentially too messy, I don't want to breathing pastel dust in a closed car, casein smells to strongly, and I'm not good with acrylics or watercolor.

The gouache seems to have potential. It dries very quickly but can be re-wetted/re-worked, which allows modification of edges. I haven't quite learned how to handle the color/value shifts that occur during the drying process, and haven't found brushes I really like yet. But I can see doing a lot more of these.

All of the above are 4x6 inches (except the next to last one which is 3x6), and are done on a medium gray matboard. I've cut the board into 8x10 inch pieces, and during painting I mark the edges with tape, put the matboard on a standard office-type clipboard which is then clamped to the steering wheel. It is cramped, but working small makes it do-able.
