I'm trying my dream cosplay as Raffaello from chocobo dungeons this year and i'm really excited for it. I have the arms and legs done. the armor on the upper arms done. I have a good idea on how to do the pants and a good enough idea on how to do the muffler. What I need to know is how the heck can i make a(only 1) wing like his and have it attached to my bare back?! please if you have any idea on how i can do this please tell me.

here's a pic of him if you don't already know what he looks like.
