LOL this is the cast on my broken ankle. It was just a white cast that drove me nuts, so I had to add some color to it. I'm sorry if it is hard to tell what it is. I found it kind of hard to draw on my leg with out causing my self tons of pain. LOL I also had to use a mirror to draw half of it because I don't bend to well. So, yes this is my take on a koi fish pond.
What I used was one cast(LOL) and about 12 Bic permanent markers
And again I am sorry that it is hard to see.
