Is this 3-over-1 twill? Is this a different fragment or the other side? Gian Marco Rinaldi tells us this is the warp side. Also look at the two pictures shown below as well from the 11:31 mark in the video at:

We need a better understanding of this.
I know that the two sides of the Shroud are very different; unfortunatly I can not find a close up photo of the backside from another source.
A question for Jull: how could his laboratory preserve a piece of the Shroud if they did not know wich sample was the original Shroud?
Zurich sample, Z1-Z1.1 Z1.2

The image from Zurich sample is very interesting: it shows the differences between the two sides of the Shroud (Z1.1.1 is from the top, the others photos seems from the backside).
The photo shows also a reweaving.
Halfsample Z1.1 (25.9 mg.) was divided in three subsamples (4.8+7.2+11.2): is there something wrong? are 2.7 mg missing?
We know that Zurich laboratory made 5 datations; in the photo we see three subsamples; where are from the other two subsamples dated? Have they divided Z1.2 in two? but a ca. 13 mg. sample is a waste of material if they have dated a 4.8 mg sample.
So it’s very likely that also Zurich laboratory retained a Shroud sample.
According to Dr. Remi Van Haelst in the Arizona laboratory: “The sample was
cut in four pieces, who were weighted after chemical cleaning, by Dr. Toolin :
13.86, 12.39, 11.83 and 14.72. mg”.

Who gave this information to Dr. Van Haelst? I think that an information so precise could came only from the laboratory itself.
But is the 12.39 mg. sample weighed by Toolin the same that now Jull have analyzed (Jull’s sample has the same weight)?
This is very important because this information says us that this sample was chemical cleaned!
In the Tucson laboratory there is much confusion.
