The Worship Network

From invitations to wedding favors, the I Do Foundation offers engaged couples an opportunity to "celebrate generously" and raise money for the charity of their choice through direct donations and charitable gift registries with major retail partners. Since its launch in 2002, the I Do Foundation has granted more than $6 million to charities like Big Brothers/Big Sisters, Habitat for Humanity, Amnesty International, and many more.

"It is our vision that, in time, charitable giving will become an integral part of the culture of weddings and other life events," writes the organization. "By incorporating a charitable focus into life celebrations, we help families establish a pattern of giving that will last a lifetime."
