Due to my mother's recent cancer diagnosis, we have decided to decrease the number of wedding guests to family only to help with cost. The only problem with this is we have already sent out our save-the-dates to our 350 guests. What is a cute/witty way of notifying our guests of this so that nobody thinks anything "wrong" has happened? We are not yet ready to announce my mother's diagnosis to the world. Note: our wedding is in October....
