learning at Penland April 3, 2015 I had an outstanding learning experience at Penland School of Craft and a JOYFUL time. We jumped right in as Lisa Colby taught us sawing, piercing, filing, sweat soldering and heat riveting.We made name tags!!! "bj" with heat rivets. I LOVE heat rivets! Happy to be at Penland School of Craft in the Metals studio!
