How do i scatter petals with no flower girl?

I don't want kids at the ceremony. We saw those "flower guy" videos and asked an adult female friend to be Flower Girl. She declined.
Without her, we're leaning more towards no flower girl at all (it's already a large wedding party so it's really not necessary). BUT I really want there to be flower petals scattered in the aisle when I walk it (yes, even though they're dirty, can stain, slippery, etc). How do we get petals scattered before I walk without a designated person to scatter them for me?
Best idea I have so far is I could have bridesmaids carry baskets and scatter petals while they walk, but right now I'd rather have them carry bouquets so I'm taking ideas as I consider. Thanks for the help!
