June Impson is a Professor Emeritus from the Texas Woman's University.  Although she paints in several media, her current preference involves a unique technique she has devised through experimentation, trial and error.  She would be the first to say, "Lots of error!"  She uses discarded watercolor paintings, coats them with a mixture of matt medium, marble dust, and water.  Over that dried surface she loosely sketches her composition with charcoal, mostly ignoring the previous watercolor painting that softly shows through the rough marble dust undercoat.  She then washes in color with gouache and/or watercolor, still largely ignoring the previous painting that shows through.  Over this dried surface she then creates the final pastel painting.
