I am getting married in Florida, in February next year at a Riverfront restaurant. We are water people... boating, fishing, sailing... Was going to do Horizone Blue dresses with white, blue and green paper lanterns and maybe use seashells and starfish in my centerpieces. My question is, how much do the invitations need to match? Found some cute navy blue background invitations with cute little fish kissing on them. It's not the same color blue, and it will probably be the only time that fish are used. Help!!!
