One of my favorite resources discovered in researching how the Bayeux Tapestry was made is: The Bayeux Tapestry | A look at the physical aspects of this piece from a 21st century viewpoint
This is an awesome website.
It presents, in clear and concise detail, the effort it took to construct such a monumental artifact. The author – an experienced embroiderer, member of both the Embroiderer’s Guild of America and the CT Weaver’s Guild who also worked for the Metropolitan Museum in NY setting up their Shaker textile exhibit – has a wealth of knowledge on ancient methods of weaving and embroidering.
This website provides details on the history of weaving and embroidering, ways of dying cloth with minerals and plants. The author writes about women embroiders from history, about steel needles and embroidery stretchers and fine medieval looms. She writes about wool and linen and flax. She writes about the sort of embroidery stitches represented in the Bayeux Tapestry. There are clear illustrations of what those stitches look like and how to duplicate them. Along with descriptions of the Bayeux Tapestry, she gives her estimations, from experience, of how long it might have taken those Canterbury nuns to complete such a mammoth task.
I highly recommend you give this site a look. It’s fantastic!
