This is the kind of crazy mess that attempts to request that the woman be tied down to the cross got me. The duplicate arms weren't a common flaw, but all manner of wild and ineffective rope use would happen over and over again.

What to do?

I still have access to some online service, and for as little as US $0.40 could have multiple rendering models take a shot at getting the ropes right.

But not on the whole body and whole cross at at once. The service I was using doesn't even allow simply nudity, forget about anything much spicier.

And even if not for the nudity restriction, I never got both hands and feet right at the same time in previous tries, so I used just a clip of the woman's feet, and then a clip of just her hands, in separate trials.

I soon had, as separate pieces, reasonable good rope work for both the hands and feet. I copied those bits as pieces as pasted them over the no-ropes image, using resizing and warping and then a bit of touch-up to have a single image with everything right.

Oh, and after the woman was lying on her back her tits didn't look as big, so I asked for a boost there from Gwen Image Rapid Edit. It went a little overboard, but I can live with it.
