I'm tempted to order a stamp with our return address on it for the invites. I understand it would be weird to put my changed name on it since it hasn't been changed yet, but would it be weird if I just put our first names on it? Like: His & Mine. And does it matter whos name goes first? While the invitations might be on the more formal side (in theory, haven't made them yet), we're not going for full on formal either. I was also thinking for future use, which is why I don't want to just put: First Last & First Last
