Patriotic
For a simple design idea, consider painting your boards to look like American flags. This only requires three colors of paint, and the lines can be drawn with a straightedge. Instead of drawing the stars by hand, use a stencil for consistency. Other patriotic ideas include designs that represent individual branches of the military. For instance, a set of boards decorated with a military emblem would make a great gift for a veteran or a family member of an active officer.
Sports
Because cornhole is a popular activity at sporting events, many players decorate boards with symbols representing their favorite sports. Sports-themed board ideas include team mascots, player numbers or racing sponsors. In cases where family members support separate teams, consider a "rival" set. One board and four bean bags feature the colors of one team, while the opposite board and bags feature the colors of its rival.
Pastimes
Boards can also display your favorite brands or hobbies. Hunting, drinking and fishing themes are popular examples. A hunting-themed cornhole set might include a Browning symbol and bean bags constructed of camouflage fabric. Many players choose to use alcoholic or energy drink logos. A clever take on this idea combines the two, with one board representing a vodka brand and the other representing Red Bull. Combined together, the set equals a popular cocktail.
Kids
Cornhole's simple setup and guidelines allow kids to join in the fun. Some kid-friendly cornhole games feature smaller boards that are spaced closer together. A child who enjoys participating in cornhole with adults would certainly appreciate his own personal set to play with his friends. Kid design ideas can include general interests like vehicles, animals or monsters. For a more specific, personalized approach, decorate the boards with images of a well-loved cartoon or book character.
