The art museum has been offering studio classes since the 1950s, according to education director Courtney Waring, and they’ve grown ever since. Children can study such things as cartooning and clay through various programs and camps. Adults can study drawing and painting, metals, photography and ceramics with instructors who have taught there for years. The big advantage of studying at a museum? The museum. Students can wander the galleries and sculpture garden for inspiration and insight. Wilmington, 571-9590, delart.org
