I use good artist paper as well and a laser jet printer. I sign it, put the year, sometimes month and year and a number that indicates information about the guitar. For example the image below it's my 53rd guitar 3rd parlor guitar. I've since changed that to CB to indicate that it a particular parlor guitar. But anyway I'm the only one who would ever know what that means but it might be interesting some day if it ever comes back through my shop. I typically use Titebond or White Glue. I don't remember what guitar it was that came through my repair shop probably some 20 years ago but the label inside looked like it had burnt edges adn I always liked that look so I adopted it. I use a cigarette lighter to burn and char the edge of the label.
