We are going to WDW in January, and I have made shirts for everyone except my dad. "Grandpa" won't wear anything other than love sleeve button down dress shirts and slacks. He will wear this type of outfit anywhere, so making him a shirt would be pointless. I don't want him to be left out at all though, and I would love to make something that says "Grandpa". Does anyone have any creative ideas? I was thinking a pin he could wear, but I don't know how to do that. Any ideas would be greatly appreciated!
