Don’tuse your new monogram on your invitations or any other pre-wedding stationary or decorations. Save your married monogram for post-wedding activities like the reception and thank-you cards.
Don’tprint “adult reception”, “adults only” or any other variation on your invitation. The way you address the invitation should make it clear who is and who is not invited to the wedding. Doaddress the envelopes prior to inserting the invitations to avoid indentations or ink marks on the invitation.
Docall guests if you have not received a response by the deadline. Don’t automatically assume that they are not coming, they may have simply forgotten to send back the response card.
