It depends on what you want to put on the float. It's usually a big bouquet. To tell the truth, it's not easy to do it yourself.

I found a wedding when I got married. It was good, and the price was a little over 1 thousand.

Including site layout, wedding car flowers, bridal bouquet and champagne tower.

Candle tower, flower gate, small partition (that is, small flower pier directly pressed by two flower gates) petals (sprinkled on the head when the bride and groom enter the venue)

There are brooches for the bride and groom, father, mother, best man and bridesmaid.

Something like that.

If you must do it yourself, if the speed is not fast, you can stick roses on the car. If the speed is fast, you can't use tape, you can only use suction cups.
