to your confetti. A subtle scent will disperse when tossed. Choose from
two package sizes. Large bags hold approximately 12 cups, small bags
hold 6 cups. $10 for small bag, minimum order of 2 bags $20 for a large bag, minimum order of 2 bags.
Be sure to check with your church before buying this. You may have to talk them into letting you throw this stuff after the wedding!
