Bay seniors who’d prefer to avoid the mess of carving Halloween pumpkins might want to consider checking out the large patch of brightly colored glass squashes at Cohn-Stone Studios in Richmond. They’re as glittering as Cinderella’s coach. The artists, students of the wildly whimsical Dale Chihuly, have created crystal pumpkins as well as fruit, acorns and flowers. Prices start at $20 for leaves and $45 for pumpkins. Open 10-4 Fridays through Sundays until October 28.
