Indigo is used for some traditional textile crafts in Japan, and so many of the indigo quilts were included in a section marked as, “Japanese Quilts”. Japan has a history of farmers patching things over and over again when they are old and frayed or boro. There is even a boro museum in Tokyo, and Pinterest is filled with such  boards and pins. Quilts? I think that is more recent.

Korea has a history of patchwork textiles often using the same hemp fabric that is used in traditional hanbok or even in cloths to decorate the home in a utilitarian way. It is called jogakbo. Designs and colours can be hundreds of years old but still seem very modern. I once saw a textile show at the Shimonoseki Municipal Art Museum, and it was impossible to tell what was antique and what was contemporary at first glance.
