Buttons. They may be an everyday fastener, but art teachers think they make an imaginative material for student projects, too. See what wild things your kids can conjure up with them at the Button Maker Studio. The bilingual (Spanish/English) class will introduce kids in grades 4–6 to design elements and principles as they work on take-home creations. The workshop will be held on July 30 at 3 p.m. at Rohnert Park–Cotati Regional Library in Rohnert Park. Go to sonomacounty.libcal.com/event/4051576 to register or to find out about August classes.
