If you look at football on TV, sometimes at center field they have the team logo. Maybe there is a way you could cut it in half and at center field piece together a team logo or something with the team colors! If the team logo is kind of complicated, they might have it on a T-shirt or something that you could applique to a new green strip in the middle. Just an idea.
Sorry you're having trouble with it. Would love to see pics when you're done.
