Are you looking for a fresh, inexpensive idea for favors? We've got it in the bag. Lush floral centerpiece blooms double as favors when you provide guests with waterproof bags to take flowers home in. Have cellophane ones custom-printed with a message asking guests to pick a few flowers (foryourparty.com made ours). Set them out with twist ties to cinch bags closed, and at party's end your guests can carry on (and carry off) a bit of the celebration.
