Just in time for Halloween, on Saturday, October 29, from 10 a.m. to 4 p.m., the Spring Green Area Arts Coalition presents “Monsters with Nick Ringelstetter” upstairs at The Shed, 123 N. Lexington Street, Spring Green. This is a drop-in event with no pre-registration and no age limits. All budding artists, young and old are welcome at any time during the event. All canvases and materials will be supplied. River Valley professional artist Ringelstetter will prepare canvases with backgrounds created in his signature style. Participants will select a canvas and, under the guidance of Ringelstetter and guest teacher Dick Woppert, will paint their own monster characters into the scene. A minimum donation of $15 per person is suggested to support the grant programs of the Arts Coalition.
