Like i know you're not supposed to wash it often etc, but like should I limit wearing it ? how can i make it not fade
Go over it with a good fabric marker or fabric paint pen- although that kinda ruins the authenticity of the signature if it's like signed by a band/famous person. It just depends if you mind going over it. But yeah sharpie won't last as brightly as a specifically designed fabric pen. Maybe next time you go to a concert or wherever you got the shirt signed, bring a fabric pen!
Iron or put in drier for 10 minutes or so. This will keep it bright. When you wash it, turn it inside out. I hope I helped!
you need a fabric marker and a good one... even some of the fabric markers fade after a wash...
Go over it with Sharpie after it starts to fade.
Hand wash my friend (:
