Sashiko (刺し子, lit.'little stabs') is a type of traditional Japaneseembroidery or stitching used for the decorative and/or functional reinforcement of cloth and clothing. Owing to the relatively cheap nature of white cotton thread and the abundant nature of cheap, indigo-dyed blue cloth in historical Japan, sashiko has a distinctive appearance of white-on-blue embroidery, though some decorative pieces may also use red thread.[1][2]
