Wording for a second thank you card

penguinpop

Earlier this month a cousin gave us a check at our engagement party.  I sent her a thank you saying we will put the funds toward our honeymoon.

She just sent us a much larger check with a decline on the RSVP to the wedding, but now I'm worried that sending the basically the exact same thank you - same stationary, same thank you message about the honeymoon - will seem a little tacky. Of course I want to thank her for the generous check, but I am wondering how much different I need to make this second one.

I think you could essentially write a similar thank-you, but with the added message of "Future Mr. Penguin and I are sad we won't get to see you at the wedding - but let's plan a time when we can get together in the near future!"

Ditto @sparklepants41 with a note about missing them at the wedding.

I think you can embellish the note about your honeymoon with something like "we really wanted to do XYZ on our honeymoon and now we can. Thank you so much!" (just make sure you're sincere and you actually do it)
