Next to the disused Manda coal mine, a world heritage site, there are ruins of a knitting factory building called Aso Knit. I heard that many widows who lost their husbands in mining accidents used to work at the factory. I knitted using ~25km long threads that I found at the factory. I also tied materials, which I found in the factory and the coal mine, to the knitted thread forming a ring with a ~1km circumference. And I put it through the grounds of the factory and the mine.
