The concept, they tell me, is that you put out glass vases and containers filled with different types of candy. Some people do candies in colors that coordinate with their flowers and such, but I don't know if I'm that great of a planner.
As people filter out, they make sure to fill up bags with candy to their liking.
I think it's a better idea than traditional favors, provided there is a variety of candy to be had. Anyone been to a wedding with a candy buffet?
