Rose Petal Toss for Ceremony Exit

So lucky for us we have 10 hours with our photographer. I love this because I’m having them come around 11am and then they’ll leave an hour or 2 before your reception is over...that way we’ll be able to get all of our getting ready pictures and everything else without feeling rushed. Because I am having them leave before the reception is over, we weren’t planning on doing a grand exit at the end. Instead, we LOVE the idea of having our guests on the end seats during the ceremony do a rose petal toss. This would happen after we kiss and when we are walking back down the aisle to leave the ceremony together. The only issue that I am having is I’m not sure what I would put the rose petals in that wouldn’t look tacky. I’ve included a picture of our ceremony space as well so you have a visual. The venue does allow this, just trying to find the best way to execute. We will also have wedding programs, so guests will know what’s going on too. Any ideas on how I can pull this off? Thanks! ❤️
