Shibori
In shibori, various patterns such as circles, squares and lines are created on the fabric by folding, tying, knotting and wrapping. Depending on the type of folding and tying, as well as the strength of the squeezing, the colour does not get into the fabric at these points.
In our example, we taped cardboard rolls together on the long sides, placed the long roll on the dry cotton bag, rolled it up and knotted various ribbons around it.
Then dip the entire bag into water, wring it out and place it in a bowl or tub. Now shake the textile dye well and apply it to the fabric. After drying, cut the ribbons and roll out the bag. Allow to dry again if necessary. Then iron to fix.
