In this four day seminar, September 6, 8, 13 and 15, taught on location at the Natick Community Organic Farm, 117 Eliot Street, Natick, and in the studio in nearby South Natick, learn to paint economic plants grown locally.  Take your observations from the farm’s fields back to the studio to portray the plants in drybrush watercolor.  Sarah Roche’s expert instruction will fine tune your drawings to be botanically accurate and expand your watercolor skills to capture textures and tones and the vibrant colors of fruits, vegetables, and foliage. Your paintings will look good enough to eat.   Watercolor and drawing experience required. Foundations or equivalent course required. Work at your own skill level in this class for advanced beginners to experienced watercolor artists, sponsored by the Wellesley College Friends of Horticulture.  WCFH members $250, non-members $300 – to register, log on to www.wellesley.edu/WCFH, or call 781-283-3094.
