Ok, Save the date time - though this is pertinent for invitations.
I have very good cursive handwriting & pretty good calligraphy skills, so I'm of course hand addressing all of our invitations. It's the one area of wedding planning I won't let FI touch, except maybe to lick the envelopes and add stamps. To make it easier on me, FI got us a custom rubber stamp with both of our last names and our address on it to use for the return address, and possibly the address on the RSVP envelopes.
(Something like this
, but with a simpler design and both our last names.)
Is it etiquette-approved to use these? I can't imagine anyone on our guest list caring, but I'm curious. Is it ok for informal (STD) mail but not the formal invitations? Should I hand-write our address for RSVPs?
