I'm sorry, I know that this question has come up before, but I'm wondering how to do my escort cards. I used titles and addressed invitations formally as Mr. and Mrs _____, and we're having an evening wedding/reception, but I would really prefer to use first names on the escort cards. My question is, should I use full formal first names, or the nicknames that guests go by? Elizabeth vs Beth, Daniel vs Dan, etc... thanks for your opinions!
