Has anyone here made escort cards using retro/vintage hotel or motel keychains? I'm trying to look for the most cost effective way to do this without just using cardstock. I'm attaching skeleton key bottle openers to them, but I want each keychain to have have our guest's name and their table number as their "room number". Most websites is a bulk order for one design rather than an engraving for each person's name and table number. I'm also doubling these as my guests' wedding favors so I don't just want to use cardstock.
