The subject of Mary’s painting is an old aspen tree she found while hiking near Mount Evans in Colorado. As usual, she used the Venetian painting technique which is very time-consuming. She started with a charcoal under-drawing. The under-drawing was then covered with an under-painting or grisaille. After that, she spent months adding layer-after -layer of pigments and glazes working from the dark pigments to the lights. The painting is oil on canvas and is 36″ x 60″.
