So, I just got married in Punta Cana and we gave all of our guests who attended a welcome bag which included a few thank you gifts and a thank you note. We did not ask for gifts as their presence was our gift. Being that we provided the welcome bags with the thank you notes, do we still need to send out thank you cards to those that attended even if gifts were not given? Some guests who attended already provided gifts for my bridal shower and I have already sent the thank you cards to them.
