I know, I know....I'm probably behind on this whole STD thing, but I am waiting until the first week of January to mail out my STDs. My envelopes from envelopes.com (highly recommended, by the way!) came in yesterday and I have a personalized return address stamp that I ordered from Etsy, which I LOVE, but now I'm not exactly sure how to address the STDs!
How formal do they need to be? If I'm addressing one to a married couple would it be written: "David and Amy Smith" or "Mr. and Mrs. Smith" or "Mr. and Mrs. David Smith" ?
SInce they're STDs and not invites, I'm sure they don't really need to be very formal...right?
Thanks in advance
