When the National Folk Festival returns to Greensboro on Sept. 8-10, most of the attention will be on the artists making music on stages throughout the downtown area. But the festival also gives an outlet for other, equally gifted artists to show the public what they can do. The National Folk Festival will include nearly 20 local craftspeople, who will have a wide range of handmade items (both traditional and contemporary) for sale at the festival’s North Carolina Arts Market
