VESSEL VISIONS: Asheville-based mixed-media artist Heather Allen Hietala shows 14 works in the group exhibition Outside Inspiration at Blue Spiral 1. “The vessel in all its many forms is [Hietala’s] muse,” says a press release for the show. “Seedpods, canoes, paddles, sailboats, weaving shuttles and kayaks are part of her personal history.”
