Just skin it,flesh it and stretch it out on a board and let it dry,I use thumb tacks but you couls staple it.Then when it is dry,won't take long cut it loose and roll it up.Thats it. You can take the scales off after it is on the bow and dry,at least that's the way I do it,then seal with Tru oil buff light between coats with 000 steel wood, from head to tail,keep coating it untill it is smooth,depending on the snake,some take a lot on some not so much. Alos I glue mine on with TB3.
