We stumbled upon this helpful list of the top 10 wedding mistakes (many of which relate to invitation etiquette) and thought we’d share a few. Hopefully we can help stop you from making the same mistakes. Calling your friend’s significant other “and guest” when you’ve met that “guest” at least twice. Extra loser points if your friend has been with that person longer than you’ve been with your fiance. Consider yourself ex-communicated if the “and guest” was invited to your shower and bachelorette. Including a return envelope intended for monetary gifts. Believe it or not, this happened to a friend of mine. If this happens to you, take a small stack of Monopoly money and place it in the envelope. Affix a note to the “cash” that reads: “Sorry, I am uncomfortable sending real money through the mail.” Stapling your registry cards to the wedding invitations. Imagine the glee that spread through my soul when I heard this story. Really… I mean, really? The practice of including registry information in a wedding invitation is dubious yet acceptable, however, invitation+registry card+ stapler should never meet. Including blank RSVP cards. We’d all like to believe that our friends and families are smart. The simple fact is, they are not. Which means if you include blank RSVP cards, except to receive several blank ones back and several more with just the number of guests and no names.
