Scripture calls it a "napkin".
I don't believe the shroud is real
It’s a very interesting thing. Scientists thought they had it whipped with the first test, but they tested a piece of added material.
But that’s not the real problem for scientists. They are flummoxed by how the image was put on the cloth. It does not penetrate the cloth at all, like paint or any other added substance would. It sits on top of the fibers without entering them. They can’t explain it except to say it may have been caused by a sudden powerful burst of light which lasted for a VERY short period of time.
It’s...interesting.
Have you looked at all the available evidence?:
Scripture calls it a "napkin"
The Shroud is purportedly the "burial cloth" of Jesus. The "napkin" was a separate piece of cloth, probably the one used to bind up the jaw of the dead person (John 20:7).
There are two cloths. The body wrapping one (shroud) and that which is wrapped around the head to hold the jaw up. The latter is the "napkin" referred to. Scripture notes that the napkin was placed separately from the shroud.
Jesus was buried by two men, Nicodemus and Joseph of Arimathea. The Bible records that some women were observing the process. There's nothing about anyone being "confused" or anyone doing anything "hurriedly".
What practice are you referring to that "doesn't allowed for anyone to pick up a body, lay it down on a VERY large and flat sheet, and fold it over the body"?
Your "analysis" is rather puzzling to say the least.
