**Went to a conference on the Shroud.**
I’m guessing that they addressed the separate napkin that was about Jesus’ head. (John 20:6,7)
I assume he was “bound hand and foot with graveclothes: and his face was bound about with a napkin”, just like Lazarus (John 11:44).
Lazarus managed to “come forth” in his linen bound condition, but was apparently still bound enough for the Lord to order him loosed from his grave clothes.
Not swearing the shroud to be a fake, but people were not stupid 1900 years ago. A mortician making it with the aid of a dead man’s corpse, well..... Not me, I’d never do it.
Well as it’s said: You had to have been there. Four and a half days.
