Tire Brand Silk Thread - Set of 25 100% Silk 20 meters Size 16 I primarily use this for sashiko. The smooth, silky feel allows the needle to glide easily. The thickness is greater than Daruma household thread (fine) and similar to a thin sashiko thread. I've included a reference image for comparison. Although these are old, there is no visible deterioration of the thread. It's a strong thread and cannot be torn by hand. Some of the sheets have yellowing, but please understand.
