To think of your sending us all this wonderful glass! It is simply, divine, and Jim and I both thank you a thousand times!
The presents are, of course, to be shown on the day of the wedding, but do come in on Tuesday at tea time for an earlier view.
Thanking you again, and with love from us both,
Formal

Dear Mrs. Gilding:
It was more than sweet of you and Mr. Gilding to send us such a lovely clock. Thank you, very, very much.
Looking forward to seeing you on the tenth,
Sometimes, as in the two examples above, thanks to the husband are definitely expressed in writing to the wife. Usually, however, "you" is understood to mean "you both."
