Sustainability. This is a piece called Norwegian Sweater by Celia Pym. She took an old, damaged jumper that couldn't be worn and repaired it to create this. It reminds me of the 'make do and mend' attitude people used to have - proof you can turn something that is no use to anyone into something beautiful and functional again.
"A certain love of roughness is involved, behind which lurks a hidden beauty, to which we refer in our peculiar adjectives shibui, wabi and sabi. .. It is this beauty with inner implications that is referred to as shibui. It is not a beauty displayed before the viewer by its creator .. a piece that will lead the viewer to draw beauty out of it for themselves. ~ "The Unknown Craftsman: A Japanese Insight into Beauty", Soetsu Yanagi, Bernard Leach (Mandala of Mending by Junko Oko)
