"I had this vague conviction that every human being was born an artist, but that his or her gifts could be brought out only if artistic activity was encouraged from early childhood by way of practising a craft... The creative energy of the average person is being sapped by a conformist system of education and the extension of industrial technology to every sphere of modern life."
The weavers (adults now) use these large looms to create the wool tapestries. They can work either horizontally or vertically, and as they go the work is rolled onto the lower bar, so they never see the entire work until it is finished. They never use any cartoon or drawing, but instead improvise as they go along. You read that correctly - this work is improvised, even though they can only see the small section that they are working on, which may even be sideways, such as the one in the next picture.
The weavers can work on each image independently.
And this final one was a huge landscape, obviously done by a very experienced weaver. If I remember correctly, it took the artist a year and a half to create.
