Now highly collected, beautiful Japanese Boro,which basically means rags or scraps of cloth, were made out of necessity not design. It was the need to stay warm and the patience to repair that created these lovely fabrics that we now consider an art form.
These fabrics were precious, they were made from the hemp or flax that people had planted, harvested, spun and dyed themselves. Therefore when clothing and bedding needed to be repaired, patches of other fabrics were stitched over worn areas with tiny 'sashiko' stitches to secure them in place.
For the poor of Japan up to the early part of the 20c, clothing had to be maintained throughout the wearers life. Boro was born of the value of 'mottainai' an ancient Buddhist term from Japan that means to have respect for the resources around you, to not waste resources and to use them with a sense of gratitude.
