The artists do live demos for free in their studio. Beatuiful, amazing glass art. I commissioned them to blow a piece for my wife as her anniversary gift and then we went and watched them make it. She loved it. The guys are very friendly. They tell you what is going on and answer all your questions. Hours are sometimes inconvenient - they're only open Tue nights, Thurs nights and Saturdays all day. But it's worth it...even if you're 6 hours away.
Pros: beautiful art, entertaining, unique
Cons: hours of operation
