Besides the obvious main invite (names, date, place), RSVP card, what are the other important things to have with your invites?
For my brother’s wedding invitations, we did the main invitation and added corner copy to state “reception to follow.” The inner envelope had each invited person’s name, and the outer envelope had their mailing address. To save on the expense of additional stamps, the RSVP card included an email address to RSVP to. If your guests are local, that’s all you really need. If the majority of guests are traveling, an information card would be ideal (or you can utilize a website).
