Replying to @someday paper co I recommend using a non-machinable stamp and asking for hand cancelling when mailing wedding invitations with a wax seal. Why? Because I am a Cautious Queen. I’ve mailed single cards with a forever stamp and a wax seal, without issue. Receiving my friend’s save the date from across the country was further proof that this could turn out perfectly for you, too! Just remember that USPS is an Inconsistent King and set your expectations accordingly. #savethedate #mailing
