This is clasic 100% cotton sashiko thread. It is 6-ply medium thread made by Olympus. Each skein has approx. 20ｍ in length.  Suitable for all your sashiko projects. This thread is not mercerised, so it feels slightly thicker than the 100m mercerised sashiko thread. It also feels softer and has a beautiful matte finish, which is thought to be more like antique sashiko threads.
