My wedding shower was yesterday and I'm finally down to my last few thank you cards! I received a gift from FI's aunt with the names of his two cousins signed to the card. The cousins were invited but both live out of state and I know the gift is entirely from the aunt. Do I need to send 3 individual thank yous (one to the aunt and one for each cousin) or can I send I thank you to the aunt's address thanking all of them? I could easily go either way and I'm just looking for some opinions. TIA!
