We were married last November and had just a few guests (approximately 5) attend our wedding who did not give us a gift. We searched etiquette boards extensively and decided to send thank you notes to everyone, including those guests, with their note expressing our gratitude for their attendance on our special day. Just recently, we received gifts from two of those guests. Should we be sending them a second thank you note now, or is that just weird? Should we instead orally thank them for the gifts? Thanks!
