I'm reading that 'proper' etiquette says if you're addressing the outer envelope to:Mr. and Mrs. John Smiththat the inner envelope should read:Mr. and Mrs. SmithI feel a bit strange doing this for at least my immedate family. People I call Mom and Dad I don't really want to be that formal. FI suggested for our immediate family we just put first names and "Mom and Dad" for our parents, and for everyone else do it the Mr. and Mrs. Smith way. How have you gals handled this?
