I used some Halloween black feathered wings I found on sale, and ripped those apart. I used a heavy leather circle I made into a flat collar as a base and arranged the wing pieces artfully. I also used a feather boa and some extra dyed black turkey feathers to fill it out. One of the few projects where I used hot glue which is great for feathers. I put huge blue plastic stuffed animal eyes on it and turkey skulls to hang off it since it was based on the low/mid level zealot shoulder from Warhammer Online.
