Paper Dartboards
Wooden dart boards are made from end grain pieces of basswood.
Wooden dart board comes in two sections, a center section which is a circular area that includes the blue rings, and an outside "frame" area. The center section will rotate, although it usually takes a bit of elbow grease at first.
Since the same innings are often used over and over, wooden dart board wears unevenly, to prevent that, you can rotate it which will let dartboard get as much life as possible.
