It’s hard because you’re hanging it according to what you’ve seen - try it hung from the front legs: make an incision in the skin, from inside the joint where you’ve cut off the foreleg, and run it down inside the armpit area, all the way to where the windpipe and gullet were removed, repeating the process for the other foreleg; after peeling back the first inch or so on both wrists, make a crossing cut just above this lower leg ‘wrist‘ joint, in the area full of sinew, appx 1cm above the flat lint you removed the foreleg at - this is where your snare, dyneema or wire loop will hold on to the foreleg without sipping off - the loops can slip off if you don’t do this - then hang up above head height, preferably from a fixed handing point as opposed to a fully swivelling one, and start peeling away, shoulders first. The neck can be a little tricky, but with the minimal use of the knife you should be able to take the hide off completely, and with minimal meat damage or loss, nor hair or fingerprints left on the carcase. Use this method a few times and you’ll be wondering what the videos etc are about, and why you hadn’t tried this method earlier.
