sashiko is a traditional Japanese embroidery technique that originated in the Edo period. It involves stitching simple geometric patterns using a running stitch, often with white thread on indigo fabric. Originally, sashiko was used to reinforce and repair worn clothing, making it both functional and decorative. Over time, sashiko evolved into an art form, with intricate designs and patterns that reflect nature and daily life. Today, it is appreciated not only for its beauty but also for its connection to sustainability and the practice of mending, aligning with modern values of upcycling and slow fashion.
