COSMO Sashiko Cotton Linen Multi-Cloth - Cross Stitch - Brown Thread-ito- Sashiko Thread 20/8 20/8 is a fairly thick sashiko thread. For those who are okay with thick thread, please consider it (*^_^*) I love sashiko so much that I've collected too many supplies. I have a lot, and it seems I'll have less time to enjoy sashiko. I decided to sell some to organize my collection. I hope you find a good match!
