use a utility knife with a roofers hook blade to cut through the belly scales from neck to tail. cut around the neck through the skin to get started . hold the head in one hand, and the skin in the other and pull the skin from the body. once you have done this, stretch the skin on a board, flesh side up. use push pins to hold the skin down to the board. make it as straight as possible and make sure it is stretched tight. now it is time to flesh the hide out. you can use a spoon or a dull knife. just be careful not to cut through the hide. depending on the weather in your area it could take several hours to a few days for the hide to dry. then cut the belly scales off , roll up and store in a ziplock bag for future use.
