Looking for fun ways to give away the Centerpieces

I would make sure family and wedding party has first dibs on them

Maybe put little signs by them? Or maybe have the DJ make it into a game somehow? Like longest married couple gets to pick the first?

Oh absolutely - good point. We're going to have 24 floral centerpieces and 24 smaller vases with ferns and moss.. there will be TONS to go around.

Sticky note that says winner under a chair?

As long as you're not renting the vases/containers!

A colored dot under the coffee cup -- easier than everyone looking under their chairs.

Great ideas! Good point about the coffee cup Nancy, that'll definitely be easier.

You could do a mark at their seat like others have said. I've also been to two weddings that the person with the birthday closest to x date at each table gets to take one home
