It is a great idea to print custom stickers for sports fans. You can print the school logo and mascot with a football, soccer ball, softball, tennis racquet, etc. The list goes on! Hand them out at games or have the players hand them out at school. This will undoubtedly help with game attendance and encourage players to have good social skills.
In addition to sports stickers for fans, it would be conducive to make custom labels for sports players’ water bottles, bags, helmets, or other sports equipment that would need names or specific labeling.
