Picture moldings are an architectural detail made popular by Victorian homeowners, who presumably didn't want to punch holes in their walls. To fashion a wall worthy of a gallery, team the moldings with decorative hangers.
Decorative picture hangers add personality and lead the eye to the art. This hanger is a Victorian antique.
Original Victorian picture hangers, such as this one, are becoming difficult to find.
Invent your own picture hanger by gluing a pretty drawer pull to an S-hook.
