I found a photo gallery for a peacock themed wedding, and I love how they did it! The feather were used in just the right amounts (I was worried about things getting out of hand, lol). The only thing I think I will change is to use the deep sapphire from our wedding colors (sapphire and avocado), and make the deep purple more of an accent. Just curious to see what you ladies think!
