If you want to honor your background and heritage at your wedding, there are several ways to do so:
Pay tribute to your ancestors. One way to do this is find out what your parents, grandparents and great-grandparents did at their weddings. Then, select an element from each of them to replicate at your own. For instance, your centerpieces can mirror the ones your parents had. This can also be a chance for you to find out about hubby-to-be's family and to include relatives from both sides in the planning process.
Have diverse treats. Create a "goody station" with desserts from all the countries that are a part of your heritage. Place small flags or description cards so guests will know which treats came from where. You can also let guests take some goodies home with them.
Establish your own traditions. Another option is to begin a continuing tradition that only you and your spouse do starting on your wedding day. For instance, you could slip a cute love note to one another right before the ceremony begins, and do it each anniversary.
