Mistakes are made and serious ones. That pajama folding experiment was impossible, if not a fraud. The matter is explained at this website:

So, even by the time of the trial four years later, the defense and jurors were still unaware that alignment and directionality were incompatible – since the prosecutors did not disclose the opposing findings of the (FBI and CID). They were told only that the 48 holes were made to align over the 21 wounds. Had the defense and jury been privy to hear this irreconcilable information, the outcome of the trial may have been very different.
Nonetheless, Doctor John Thornton, a forensic scientist (now Emeritus Professor – the highest standing) from the University of Berkeley, California, was retained by trial defense attorney Bernard Segal. Thornton pointed out to the jurors that Stombaugh and Green had failed to account for the number of other ways there might be to fold a garment, so that 48 puncture holes might align over 21 stab wounds. He also pointed out to the jurors that the prosecutors had not accounted for the holes made in Colette’s own pink pajama top, which lay between the blue pajama top and her bare chest. This garment, worn by the murder victim, amounts to a missing piece of a jigsaw. By not accounting for this garment, the experiment, lacks any scientific validity.
