I am making the centerpieces myself – and while I don’t care if the flowers are there when the night ends, I am planning on using the bases and other décor in our new house. At almost every wedding I have been to I have seen guests take centerpieces home with them – I’ve even seen guests fight over taking one home! Is this common practice? If so, how can I politely let my guests know that my reception décor is not an additional wedding favor? I am giving out bottles of wine for favors, so it's not like I'm being "skimpy". TIA!
