We had big ice boxes with the wine in it as our centerpieces. The tables we were given to use were different because of covid and very tiny so having it be functional was perfect. I’ll see if I can find a photo
Maybe lights, tealights, candles or lanterns. We aren't allowed candles only LED lights but there are a lot of nice ones. Is there anything you both love? I've seen some really cool centerpieces where they used books. The wine bottles painted to your colours look nice too. Would you add greenery or no plant materials at all?
