The Shroud is not paint, and what you said does not make any sense...
You would have to paint your ears, fold a fabric over your ears and lay it out, and I have never seen someone do that on a peice of cloth...Have you?
And as my statement, why would a sheet stay straight out over a body and now settle down the sides. At night does not your sheep drape down the sides and around your body? Now if by some miracle it stays flat, that would explain the picture. I don't get your problem with logic and common sense.
