I'm currently working on five main series of paintings:
Shields, Imagined Systems, Glyphs, Taped Shapes, and Natural Earthworks.
Naturally, elements of any one of these series can invade any other series at any time. I'm working almost entirely in improvisation. Generally I'm not doing any planning, sketching, or even pre-thinking of what will come next. I love surprises!
Often I find myself drifting solidly into one of these series, and it seems like some of the others may have dried up. So far that has not happened. It is a great joy that they all tend to cycle back into my flow of painting eventually.
