One of the best way to leave an open reminder to your guests is to have great wedding centerpieces, think of it this way - this will be the focal point for most of your guests as they will see it most often. Most of your wedding guests will chat and bond over their table and most certainly will continuously interact with your centerpieces. So instead of thinking about it as secondary decorum you should actually see it a a main source of inspiration.
The best way to make an impression is to opt for a style of decorum that not many have used before. One of the trends that I personally like this year are branches used as centerpieces, you can either incorporate them into bigger flower centerpieces or you can use them individually. Also by using branches you can create a pretty wedding tree where all your guests can live their best wishing cards.
