Indigo Dye Embroidery Obi Belt Indigo dyeing doesn't immediately turn the fabric indigo like chemical dyes. Immediately after dyeing, the color is greenish, and it changes color by reacting with oxygen in the air. To dye a deep indigo, the process of exposing the fabric to air is repeated. This change in indigo color is why it's said that "indigo dyeing is alive," and it has been loved by Japanese people for a long time. There are slight signs of wear from tying the obi, but there are no problems with wearing it. Length: 442cm Please understand that this is a private seller's item.
