Activity for Heidi

I need help to find or come up with something else for centerpieces because the flowers I would like for centerpieces are expensive. Going to have some flowers but need another idea to cut the price down. Any ideas? Appreciate the help!

Don't have a set date yet. Looking a venues this week. Got nothing booked yet. Am I considered behind on planning? I feel like I am and my FH doesn't think so. What should I plan first? Looking for date to be at the end of May or beginning of June!
