Howdy, I apoligize for the late reply . combination of computer probs and 2 jobs and camping keeps me away from here for a while. All I did was skin it and stretch it on a board with pushpins , salt it a lil bit and put enuff glycerin on it that it soaked thru. Good luck.......Bill
p.s never rinsed cause I had cut the head off and bled it before I skinned it
