So, this time I made extensions that could be added to any purchased wings. Bigger is better. The ones I used measured 36" x 24". I will give you links to purchase the wings that I used. Although, in the 8 months since I made these wings, they are no longer available where I bought them ... grrr!
Annie's Costumes has the black wings. And ... well I can't find the exact wings I used in green, but Amazon has something close. Again ... grrrrrr!
So, here is how to deal with wings that may not be the exact color you want, because even though I was able to get big green wings, they were not the shade of green I needed. And the shoulder straps were the wrong color, too.
