“The positive test for vanillin as well as the presence of cotton actually spliced to linen and tinted as discovered by Ray Rogers establishes that the sample site selected for the 1988 C-14 test was anomalous and moreover that it was young. The reasons for this have not been firmly established. One theory set forth by Joe Marino and Sue Benford is that the site contained an invisible patch. This thesis is controversial, however it currently constitutes the main theory for why the region is anomalous.”

*"New scientific tests on the Shroud of Turin, which went on display Saturday in a special TV appearance introduced by the Pope, dates the cloth to ancient times, challenging earlier experiments dating it only to the Middle Ages.
Many experts have stood by a 1988 carbon-14 dating of scraps of the cloth carried out by labs in Oxford, Zurich and Arizona that dated it from 1260 to 1390, which, of course, would rule out its used during the time of Christ.
The new test, by scientists at the University of Padua in northern Italy, used the same fibers from the 1988 tests but disputes the findings. The new examination dates the shroud to between 300 BC and 400 AD, which would put it in the era of Christ.
It determined that the earlier results may have been skewed by contamination from fibers used to repair the cloth when it was damaged by fire in the Middle Ages, the British newspaper reported. The cloth has been kept at the cathedral since 1578.
He also said his tests also supported earlier results claiming to have found traces of dust and pollen on that shroud that could only have come from the Holy Land.
The latest findings are contained in a new Italian-language book — Il Mistero Della Sindone or The Mystery of the Shroud, by Giulio Fanti, a professor of mechanical and thermal measurement at Padua University, and Saverio Gaeta, a journalist."*
Yes, especially to the naked eye. That is the beauty of the art of invisible weaving, using the same material, or material made to mimic it (cotton), and following the exact type of weave pattern.
