Tsutsugaki (筒描) is a Japanese technique of resist dyeing that involves drawing rice-paste designs on cloth, dyeing the cloth, and then washing off the paste.
The paste is applied through a tube (tsutsu) similar to a piping bag.
A related process is to apply the paste through a stencil, a technique known as katazome.
Banners for shops or other purposes are sometimes made in this manner.
The designs are often creatures from Japanese mythology such as the crane or the tortoise, or a family crest, or a name (written in kanji).
