If you are going to make an arm guard and cover some leather with the snake skin, you wont need to tan it soft like with the glycerin. You still tack the skin up to dry, and then when you are ready to glue it to leather you just soak the sking for a few minits in water and it gets soft again.Then you put the glue on and spred the snake on the glued leather till the glue drys and trim around the leather. May want to run a row of stitching around the edge.Or if you are carfull you can use the skin dry and use contact glue to put it on the leather.If you do use glycerin it will not glue well at all.
