Be ready to light up your jack-o-lantern on Halloween with master pumpkin carver John Bardeen! John is a passionate crafter who's been carving for 65 years. You'll learn the carving technique invented by his family as you use tools created for their Denver-based company, Grampa Bardeen's. You bring the pumpkin and the desire to learn from a master carver, and we provide the rest. All carvers welcome. For our younger carvers (age 6–12), we recommend carving with an adult.
