Black & White Wedding Theme - HELP!!!

Hi-I also intend on having a black and white wedding, however I will have silver as an accent colour. For tables I`m keeping it cheap and simple as I have a small budget-white chair covers with black ribbon tied in a bow around them and white table cloths with black and silver glitter and sequins scattered over them. I`m having glass bowls filled with floating black and white candles as centre pieces-cheap but very effective! as for favours I`m giving the guests some black ,white and silver candied almonds in little black boxes................some suggestions that may help some of you! Good luck with all your weddings xx
