Today I am so excited to present you the most fascinating, and, in my opinion, poetic method of dyeing clothes. It comes from the eight-century Japan, where indigo was the main dye used.
Shibori, known in the West as tie-dye, combines several methods of dyeing cloth with a pattern. Arashi, Kumo, and Itajime styles are among them. The first one involves wrapping a cloth diagonally around a pole or, in general, a cylindrical object. Then the cloth is being tightly bound around the pole with a wire and subsequently scrunched. The second technique, Kumo, consists of wrapping sections of cloth around found objects and bounding them with rubber bands. The last method, Itajime, is a shape-resist technique, where the dyed cloth is folded like an accordion and pressed by two flat objects, bound with wire or rubber bands.
You can find more detailed description of these three techniques here.
Shibori dyeing may sound like a complicated operation, but I am sure that if you release your creativity, it will bring you a lot of fun to go further in exploring its potential. The beauty and endless variety of patterns will be a great reward for all your efforts.
