The only thing we are allowed to throw at our ceremony is bird seed, because it's in a park, and even if you have people to pick up flower petals (real or fake) they won't let you, so our flower girl will toss handfuls of bird seed. Our guests have that option, but we also thought about doing bubbles. I'm hesitant to do bird seed because I don't want it to get stuck in my hair or dress (my dress is going to have a lot of lace on it) but I'm not sure how bubbles would look. Thoughts? Has anyone done either?
