Just What is Katazome?

Just What is Katazome?

Just What is Katazome?

Katazome is a form of paste resist surface design. That is, a paste made from very sticky ingredients, in this case rice flour, that is pushed through  a stencil to define a pattern on a length of yardage. Wherever the  paste sticks to the cloth, it will resist, or prevent, any color from staining that spot. The rice paste is resisting the color to create a design on the fabric. 


First, a design is transferred to a piece of hand-made mulberry paper called shibugami. The design is cut into the shibugami using a very sharp traditional knife and a variety of hole punches. Silk netting is later attached to the front side during the lacquering  process. The areas that have been cut away allow the paste to go through the stencil and stick to the cloth. The paper portion blocks the paste.

Since this is a repeating stencil, it is very important to match up the pattern exactly as the stencil is moved along during the pasting process. The stencil is used repeatedly in this manner, eventually covering the entire cloth  with the paste design, as you can see in the photo.


The cloth is stretched up with a set of wooden clamps and bamboo sticks called harite and shinshi.  The colors are applied one at a time–this process is called irosashi.


All  the colors I use come from natural sources such as plants (indigo, gardenias, and onion skins to name a few), insects (cochineal and lac),  and minerals (such as dirt and iron rust). Each is applied a minimum of  three times to build up depth of color.

Once  I have the basic colors applied, it is time to stop to take a look at  how well the colors are socializing with one another. In this particular  case, I realized that  the tone of the conversation is a bit more  heated than I would like, so I've decided to pacify the party with a  light wash of persimmon juice, a yellow tint that will mellow the mood a  bit.


Now  that I am satisfied with the tone of the party, it is time to pick  things up and give the piece a little more spark. This is done through a  process of accenting areas to focus the viewer’s attention. These  accent marks are called kumadori, which is the same term used by a kabuki actor in reference to the bold lines he paints on his face.


Much  darker colors are applied to specific areas of the design to accent and  embolden. The overall effect of this dance of dots is to give a base  rhythm to the entire work.

The  most difficult step of all is now at hand. That is, simply leaving the  piece alone for approximately three months. The dyes are not heat-set. They are simply allowed to become permanent stains, and this happens best through patience. The longer the dyes sit unmolested, the richer  and more permanent the final colors will be.


Once  the dyes have sufficiently cured the long awaited day has arrived – the day to wash off the paste and reveal the full beauty of months of work  and planning.

The  fabric is taken down from the rafters where it has been curing out of  harm's way, and placed in a warm, inviting bath of fresh clear water.  Here it soaks at its own leisure, patiently allowing the paste to  dissolve away. Gently the fabric is coaxed from its lulled state, to be  rinsed repeatedly, removing the last traces of any excess dye and  reluctant-to-part paste. Then, as with the spank of the newborn's  behind, it is given a vigorous swish as it is yanked up out of the water  by its selvage edge, gloriously proclaiming itself to the world.


Air drying is the final stage in bringing forth a new personality into our family of textiles.
