I have been searching and cannot find the answer to this question. I know that I should send Thank you cards as soon as possible when I receive gifts, even before the wedding. And I know that I'm supposed to send Thank you cards to everyone who attended the wedding, whether they brought a gift or not. My question is, if someone sent a pre-wedding gift, which I sent a pre-wedding Thank you card for, do I then send another "Thank you for attending" card after the wedding?
