Our invites went out last Monday (the 16th) with a rsvp date of Sept 10th (one month exactly prior to the wedding). So far, we have 20 responses, so I'm thinking we are off to a great start!!! I also marked the back of the rsvp card with an invisible ink that you can see with a special light thank God b/c we already got a decline back with just the persons last name (and there are a few families that share that name!). I can't tell you the relief we had when these were out the door!!!
