I got a Football jersey signed by 4 Pro players last year. It's just been hanging in my closet since then. I went to look at the other day and sharpie signatures have faded. I never washed it or anything. I am about to get it signed again by several players. How do I make sure the signatures don't fade this time?I got a Football jersey signed by 4 Pro players last year.
