make your own salon cape

Many times when I cannot find what I need (or if I have an idea that I want to try out), I make it myself.  Right now I want to make a floor length, black PVC cape.  Doing a quick search, I found that there's a very simple and easy salon cape instruction pattern located at http://www.fuzzygalore.biz/patterns/haircut.shtml

I am planning on having this cape used in the video shoot on the 30th, when I'm filming the "Caped Girls Gone Wild" video.
