Post wedding Thank You card etiquette?

Hello everyone! We just got married in mid September and now that we finally have time we are working on our Thank you cards, but are a little confused about the etiquette.


We wrote thank you cards & gave thank you gifts to our parents and wedding party the night before the wedding. Do we send them a thank you card after the wedding too like our regular guests? There were a few guests as well who are partners with members of the wedding party, and it feels weird to send a card addressed to just the partner rather than the couple. We also had a few wedding party members who gave wedding gifts and some who didn't (they would have physically seen us opening the gift and were thanked in person).
We just wouldn't anyone to be upset because a couple members of the wedding party got a second thank you card and others didn't, but we had 14 people in our wedding party, which is a lot more heart felt cards to do.
Anyone have any insight as to what the proper etiquette is for this? In summary what we were doing was cards to guests & cards to people who gave gifts that didn't get to see us open them. And no cards for the wedding party since they already received thank you cards & gifts the evening before, and no cards to people who saw us open the gift and were thanked in person after opening (these people were in our wedding party).
Thanks!
