“The Indianapolis Reef”

Through Oct. 31
Indiana State Museum

A “coral” reef—consisting of the work of volunteer crocheters from around the state—is displayed through the end of October. But don’t expect it to look exactly the same each time you stop in. Visitors can bring their own pieces—or pick up a handy beginners kit at the Museum—to add to the work, which is an offshore offshoot of “Hyperbolic Crochet Coral Reef Project” created for the Institute for Figuring in Los Angeles.
