Not much of a market, a cured/completed tail brings about $20. But very simple. Once the tail is cut exposing the meat/bone. I usually use a vice to hold the cut side of the tail, careful not to pinch the outter skin. Cut from top down on both sides towards the tip. Use a pair of vice grips and slowly pull down exposing the meat. You will end up with (2) individual pieces. I use regular salt and let it sit for approximately 24 hrs. Flesh/tan as you would a pelt. But you do not need to stretch it. I use hemp material to sew both pieces back together. (There's a multitude of materials that can be used as well for sewing.) Wallets/small billfolds is usually what I make, but that in tails stretching prior to sewing. (In a nutshell) I've never looked for it, but I'm sure "YouTube" may help.....fun, but time consuming......good luck.
