My matron of honor chose to take on the making and printing of the inserts to be included with the invites such as accommodations, etc. The RSVP were not included. I looked at what we had and sent them out not realizing there was no RSVP until after they were sent out. What do I do? What is the best way to handle this? Do we send out a postcard, letter, e-mail, or call? Please help ASAP!
