For our engagement party instead of receiving gifts, we have asked that they give to a charity of our choice. There are websites that you can set -up a charity registry and have your guests give online or send by mail. We will write this in our invitations:
We have chosen to share some of the joy of our engagement/wedding with charity. As an alternative to buying a gift, please consider making a donation through our Charity Registry. You can find information about our registry and all of our wedding events at www.IDoFoundation.org. We look forward to celebrating with you.
This is a good gift to consider in helping others....
