For July, children will draw on themes of favorite cats and dogs, landmarks and marine mammals in the ongoing free drawing classes led by Catinka Knoth at Rockland Public Library. 80 Union St.

Students follow along with Knoth as she demonstrates drawing a variety of motifs. Knoth gears the classes for age 6 and up, including the young at heart. She expects participants to be able to work independently for the most part. Children age 10 and under need adult accompaniment, according to library policy.

Weekly themes for the month will be: July 11, favorite Maine cats and dogs; July 18, Rockland landmarks; July 25, marine mammals.

Classes are free and open to the public, with all materials provided. The ongoing classes meet every Tuesday from 4 to 5 p.m. For more information, call Jean Young, children's librarian, at 594-0310.
