Catinka Knoth leads a weekly art workshop series for adults at 11 a.m. on Mondays in the Community Room at Rockland Public Library. This month’s workshops will take place on January 7, 21 and 28 (no class on January 21, Martin Luther King Day) and will concentrate on capturing winter scenes. Knoth provides the classes free of charge, with materials supplied. Friends of Rockland Library host the workshops, which are open to the public.
