Catinka Knoth will demonstrates drawing and painting Midcoast lighthouse and boat scenes every Mondays in August at 11 a.m. at Rockland Public Library, 80 Union St. The weekly workshops are free, with materials supplied, hosted by Friends of Rockland Library. For more information, call Knoth at 596-0069 or the library at 594-0310.

Topics covered will be: Aug. 8, Marshall Point Light; Aug. 15, sailboats by Rockland Breakwater; Aug. 22, the breakwater itself; and Aug. 29, a lobsterboat headed home past Marshall Point. Knoth will teach students of all ages to do their own variations on these subjects. She also teaches a free weekly children’s drawing class at the library, sponsored by Wendy and Keith Wellin. For more information about Knoth’s work, visit catinkacards.com.

During the first workshop, Knoth will show how to lay in a graded wash for the  sky and to depict the white forms of the lighthouse tower, the pylons and the walkway by making the “negative” shapes of the deep blue sea that shows behind these objects. One will see how the dark turret and cap of the building is created with minimal strokes. The rocky shoreline can be suggested with variegated washes and accent strokes. The dark green of Hupper’s Island in the background provides further negative shapes to define the walkway. This is a subject that needs no preliminary drawing.

Knoth paints watercolors of Maine and whimsical animal scenes, which she offers as cards and prints.
