On Saturday, November 15, the Guild of Harwich Artists is sponsoring a demonstration by well-known Cape watercolorist Ann Hart, at the Harwich Community Center at 100 Oak Street, from 2:30 to 4 PM. Ann will demonstrate her transparent watercolor technique using layering to achieve vibrant color and depth. She will have both completed works and paintings in progress to illustrate the sequence of developing a painting using watercolor to best advantage. Refreshments will be served, and all are welcome to this free event. The Community Center is handicapped accessible.
