thank you cards- last question!

i am sure this has been discussed many times- but i can't find what i need in a search.

i am writing all the thank you cards for the eng party- fiance won't do it i'm sure. so when i am writing a note to his guests- can i still write it as i would my guests? i know that you are supposed to say "fiance's name and i" instead of "we".

also, do i sign both of our names on the bottom or just mine? and do i put "sincerely" or "love" or something else?

thanks!

Re: thank you cards- last question!

I don't know if this is proper ettiquette, but I would use "we" instead of "FH & I", sign both names and use Love, yours truly, fondly based on the relationship to the person you are sending the card to.
