I am making all the boutonnières and wedding decorations for my wedding in June. I'm not having any flowers at my wedding since they are expensive. I've always loved peacock feathers, so I use the feathers to replace any traditional flower decoration for my wedding. Here's a preview of the look of the boutonnières. This one is my fiancé's, which I enjoyed making the most. :)
The groomsmen and both our mothers have similar boutonnières, but slightly different. You'll just have to wait to see those at or after the wedding!
P.S. I bought 100 count peacock feathers here.
