Senninbari
A senninbari (千人針, 'thousand person stitches') or one thousand stitch is a belt or strip of cloth stitched 1,000 times and given as a Shinto amulet by Japanese women and imperial subjects to soldiers going away to war. Senninbari were decorated with 1000 knots or stitches, and each stitch was normally made by a different woman.
