I love this idea, I was looking at alternatives as well. Since I'll be having a winter wedding, it'll be expensive to work with flowers, I want to find a budget friendly option that will look good as well.
This is such a beautiful idea Stephanie! I love how creative and unique it is to your wedding theme. You should take a look at Tiffany's idea, she's having lanterns as centerpieces: Just settled on centrepieces! Did you already choose the type of lantern? What colour will they be?
This is super cute idea! But I agree with Lindsay, as long as they know what to do with them after. Might be nice at the reception to line up all of the lanterns long the head table to decorate it too!
