6″ x 8″ Oil
Martha uses only top professional grade oil paints on a prepared support of at least 3/8-ths inch thickness (only rarely does she use a stretched canvas because when painting en plain air, light shines through a canvas where it does not penetrate a board). Her boards may be of composite, or birch, and a few will have a linen surface. She creates the majority of her boards herself, purchasing birch at a local high quality lumber yard, cutting them to size and preparing their surfaces usually with PVA Size.
“Horse Creek Canyon” is one of Martha’s favorite places in Dubois, WY, to paint en plein air in the Fall.
