Your words, Colin; not mine.
Here we go a quoting from DISQUS:
Title: "The Pope" … "sad world of make believe"
Colin is referring to a story in The Telegraph, The Pope joins the EU in a sad world of make-believe by Christopher Booker. It is an opinion piece about Pope Francis’ encyclical on the environment, Laudato Si’. It is not about the shroud. Not at all.
Who cares, Colin, right? Let’s trollishly intrude!
So Colin continues:
Fiddlesticks. For one moment I thought that might be a reference to his paying homage to the Shroud of Turin, allowing one shamelessly to plug (without splitting an infinitive) the latest Blue Peter "Make Your Own Turin Shroud" shamelessly immodest breakthrough discovery.
Simply paint a gluey cold water slurry of plain white flour onto one’s 3D subject – whether a real person or a bas relief (probably the latter for the face), imprint onto linen, then press the dried imprint with a really hot iron (linen setting). Hey presto, one gets a negative sepia-coloured Shroud-like image of one’s subject. Nope, it won’t wash out, so may well be permanent. It may even display those ‘mysterious’ 3D properties if you use dowloadable software (ImageJ etc) that excels in finding "3D" wherever there’s tonal contrast in one’s 2D image.
Maybe the children’s show will send Colin an honorary iron-on Blue Peter patch.
