Barnstars are so ubiquitous here in Rhode Island and throughout New England that I barely notice them anymore, but when a friend visited recently from California she commented on the large star adorning my neighbors' garage and, having never seen one before, how cool she thought it was.
I've always thought of them as too “country” for my personal taste, but after giving them a second look I'm revising my opinion — the tin stars have the rustic simplicity of folk art that could make them unique décor for indoors or out. Barnstars have been used as exterior decoration on barns and homes, especially in Pennsylvania, since the 1800s when they often represented the mark of the builder.
Google “barnstar” and you'll find many inexpensive sources for the stars (the star above is from Clear Creek Mercantile) or they are easy to find locally at garden centers, home and antique stores.
