Lessing Toy and Hobby (LTH) is a chain of hobby and craft stores in the Southeast. LTH operates multiple stores and is organized into two divisions: Northern and Southern. Individual stores are placed in one or the other division based on geography. Recent demographic changes in the Northern Division area have led to declining foot traffic and sales in the LTH stores.
