Children, and those young at heart, will explore farming, harvest, and seasonal themes in this September’s ongoing drawing classes led by Catinka Knoth at Rockland Public Library, 80 Union St.

The “Let’s Draw Together!” sessions, geared for ages six and up, also welcome adults. The library requests that children age 10 and under have an adult accompany them. Classes meet every Tuesday from 4 to 5 p.m. in the Friends Community Room. September subjects include butterflies and Monarch butterfly migration; farm scenes of haying and the fall harvest; farm animals such as cows, pigs, sheep, chickens, roosters, geese, and ducks; and visits to the apple orchard and apple picking.

The workshops, sponsored by local patrons Wendy and Keith Wellin, are free and open to the public, with all materials provided. Participants draw along with Knoth and experience drawing in an interactive community environment. Knoth, known for her watercolors of Maine scenes and animal drawings, also gives watercolor workshops and classes. Her work may be seen at catinkacards.com. For more information, call Jean Young, children’s librarian, at 594-0310.
