I am happy to say that the flippers arrived yesterday from Arizona.
They are made of latex and unpainted. So I will be spending some time painting them to match the mask I purchased off Ebay match. The most likely will be airbrushed with some hand painting, then sealed to protect the paint.
Once, I get these finished the remaining cloth parts of the costume will get finished. I am hoping that I debut the costume at a small event next week. If not it will wait for Spring Fling.
