My fiance and I want to do something charitable for our wedding favor, but we'd also like a small token we can give to our guests. I had an idea for donating to Habitat for Humanity and attaching a small card explaining this donation as the favor to a house-shaped cookie at each place setting. There could be 3-4 different types of house cookies, so there would be some variety. Any thoughts? Other suggestions? Seen anyone who has done this before?
