Exploring new possibility in dyeing crocodile skins, we delved into the Japanese traditional「藍染」Ai-Zome（indigo dying）techniques and have established a method of reproducing beautiful blues just like Blue Jeans on crocodile skins.
To get a deep attractive color, let the indigo leaves stand in atmosphere until the blue shows itself in indigotine, a coloring matter contained in the leaf, using which, repeat the dyeing process on the object.
Indigo is a yearly plant of a Polygonaceae family, blossoms in either white or red. To make Indigo into a dye, shred Indigo leaves into fine strips and dry them up. Over which, splash water to get fermentation started. The process of fermentation usually takes 75-90 days, and when it has been completed, you get something like a blackish cake of mud, which is called “Sukumo,” a processed form of Indigo dye.
