Jack Pine Studio is famous for their pumpkin glass art collection. Each glass piece is handmade in the United States. Get yours today at My American Crafts by Robbie Dein. Jack Pine opened his new studio in Laurelville, Ohio, in 2017. More than 30 years after his first pumpkin, and numerous other locations, he wanted to return to his roots. After developing his art as a glassblower, Jack worked at Seattle Ornamental Blown Glass.
