The last dozen years, I have been working in series of 4 or 12 paintings - like variations on several themes.
The forms are abstract and simplified mountains, mesas, rolling hills, rivers, sometimes people, kachinas, lizards, birds or fish (no snakes!). A bunch of pencil drawings are made and the "keepers" are redrawn and made into paintings.
The pallet is mostly the same throughout a series - pure color with white and other simple mixtures of two pure colors with white.
Some paintings have names. Names are derived from some of what I see or imagine when I face the painting. Sometimes I think all the other paintings are silently awaiting their names.
