One assignment from the Tilghman Island workshop was to do about ten value sketches, a term used in art for a simple drawing in black and white to study light and shadow. One sketches with single lines and then connects the lines into blocks of shadow, to analyze the design on paper.
I sketched this with two Sharpie pens--one thin point and one thick--while sitting in an Adirondack chair in a shady spot on the grounds of Black Walnut Point Inn at the southern tip of the island. Doing this loosened me up and got me thinking in terms of abstract design rather than drawing individual objects. The lesson then hopefully carries through into your actual painting in oils later.
