Decorating Boy's Locker Room at School?

We decorated last year for sectionals. It was a blast. We are also decorating for the junior high. We used art paper with spray paint to make banners for the hall and made a banner for each class with the jersey#'s or players name.The kids were really surprised. You can buy any color paint just make sure it is safe to use in the school and you can also get glitter and crepe paper. We hung the crepe paper from the ceiling with balloons! Show the players you really appreciate them and all their hard work!
