Also, I have my doubts that Jesus or an angel folded the shroud and napkin. Joseph probably folded the napkin used to clean the body and laid it off to the side. The shroud was laid down, Jesus, body was laid on top of it lengthwise and then it was folded over the front of Jesus body. So it was already folded. Then when Jesus' body was transformed into a spiritual body the folded shroud simply settled in place where it lay, because a spiritual body is not subject to the laws of nature as exhibited when Jesus walked through a closed door or wall.
Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, Jesus came and stood in the midst, and saith unto them, Peace be unto you. John 20:19
