My wedding was Saturday and I am leaving for my honeymoon tomorrow but I want to get an idea of who gets a card so I can send them out as soon as possible when I get back. I know people who attended and gave a card or gift get a thank you, but what about people who attended and didn't give a card or gift? What about people who weren't invited but sent a card and/or gave a gift? Also, what do I say to each of these groups - specifically the last two? Thanks!
