NUMBER your rsvp cards because some people write a no 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. Then you also dont have to worry about losing the cards and you can easily tell who still owes you one
great website for simple, inexpensive wedding plus this super neat idea too: 9 years ago we used the small decorated cakes at each guest table as centerpieces, in different flavors, for my daughter's wedding. The Bride and Groom went to each table and cut the first piece so that they could visit a minute and say thank you for sharing their day. It was a new idea that turned out well.
