Good advice - NUMBER your rsvp cards because some people write a note where they should put their name and you have no idea who it is! Once you get them back in the mail, go into your excel spreadsheet and mark them coming or not coming.
Organize all those wedding cards you don't know what to do with. Turn them into a coffee table booklet. All you need is binder clips & a hole punch! i like the idea. maybe not a coffee table book, but a way to organize to look at later
