The Japanese tradition of stitching, patching, mending and recycling has resulted in a fantastic tradition of peasant, or folk clothing. The ragged, textured result of all the layers of stitching is called Boro.
The white mending stitches became a decorative technique in their own right called Sashiko. Intricate patterns were stitched onto woven indigo fabrics creating bold decorative detail.
