La técnica tradicional japones de decoración de tejidos es el katagami, un método que permite adornar las telas antes de teñirlas. Un katagami (literalmente 'plantilla de papel') es una platilla hecha a mano con washi, un tipo de papel muy resistente. Ésta se coloca sobre la tela y después, con una pasta de arroz, se rellenan los huecos. A continuación, la tela se sumerge en una tintura, de modo que sólo las zonas que no están cubiertas de pasta absorben el color.
La mayoría de los diseños de Japanese Patterns están inspirados en plantillas de katagami originales. Aunque el washi es un papel muy resistente, es necesario fijar las plantillas con una malla de hilos de seda, de ahí que en los diseños se aprecien finas líneas en forma de telaraña.
ENGLISH VERSION: Japan's ornamental tradition is famous for its subdued and highly stylized motifs. Many of these take their inspiration from the natural world, with representations of animal such as the turtle, the crane and the carp -all of wich are associated with the auspicious qualities such as long life, happines and perseverance- as well as an enormous variety of foliage and flowers, especially the chrysanthemum flower is often used. Other natural phenomena frequently occurring in japanese pattern design are clouds and waves.A technique traditionally used for the decoration of textiles is katagami, a method to resist dye fabrics. A katagami (literally, a 'paper template') is a handmade stencil made of strong washi paper. It is placed onto the fabric and a rice paste is then applied through the stencil. Next, the fabric is submerged into a dye bath, so that only the areas not covered in paste absorb the dye.
Most of the design in Japanese Patterns are taken from original katagami stencils. Even though washi is a very strong type of paper, katagami stencils need to be held together by a mesh of silk threads. This explains the cobewb-like arrangements of the fine lines visible in the designs.
