Skinning would be fine - but you have to be careful.
Spareout the neck and her head, too much nerves, too much blood-vessels. Begin downwards from the shoulders, that would be fine . The tits, each in six segments. Cut around the nippels and let them on her, so they can be squeezed with hot pliers when she is nailed to the cross for much more pain she has to endure.
Also spare out the regions of her elbows and knees, hands and feets, for the same reason I described before.
And make sure you have enough very sharp and different blades: short ones to do the first cutting lines, longer ones for the skinning of her backside, legs and ass. Some with rounded tips for her stomach, one with a short and thin blade fot her tits and intimate parts.
Dont use rubber gloves, do it with your naked hands. Because with gloves you would have no good grip to her skin, the flowing blood wil make your work difficult. And look for small pincers with a good grip to pull her loosend skin away.
After you have done it this way on eight to ten women you will get an upgrade to a "Bachelor of Skinning".
Best wishes.
