For exclusive use. Cotton yarn 10/4, approximately 150g per skein, 3 skeins total. This thickness is suitable for Kogin-zashi embroidery. It can also be used for hand weaving. Please read the entire description carefully before purchasing. It is recommended to wash the yarn in hot water once before use. Tie the yarn with a figure-eight of vinyl string (see photo 3) to prevent tangling. A sample skein will be tied with vinyl string. Washing will remove dirt as shown in photo 4. The yarn will change from off-white to slightly whiter, become fluffier, and slightly thicker. In photo 5, the left is 10/4 and the right is 20/6. The 20/6 cotton yarn is also for sale, so please take a look if you'd like. This is suitable for Sashiko embroidery. Shipped via Yu-Packet Post. 1 skein: 1000 yen 2 skeins: 1700 yen 3 skeins: 2400 yen If you would like multiple skeins, please let me know in the comments.
