I just had a very nice shower yesterday during which my aunt gave me some lovely shower gifts and at the same time gave me my wedding present early so that I don't have to deal with getting it home after the wedding. When she gave it to me I put it aside and did not open it at the shower. I have read on here that early wedding presents should be opened and thank you cards written promptly so FI and I will open the wedding gift today. My question is when I am writing the shower thank you should I also write a separate wedding thank you and mail these at about the same time (possibly staggering them so they don't come on the same day) or is one thank you card OK for both the shower gifts and wedding present given the timing of them?
