I was asked for a sample piece for reasearch into the way the image was made on the Turin Shroud. It’s linen 3/1 point twill at 40 ends/centimeter. Not just the finest thing I’ve ever woven, but ‘interesting’, too, requiring minor modifications to the loom and lots of hard work. Jobs like this are useful for technical learning. It’s easy to go on doing the things that you know how to do.
