Ise-katagami is Japanese paper coated with Kakishibu( ≒ persimmon tannin).
It is then carved into a stencil and a mesh fabric called "紗 sa" is pasted onto it and used as a dyeing stencil. This product has a wooden frame to make it easier to hold and work with.
This is a stencil for dyeing one part of a kimono
The last photo shows the current work in the dyeing factory.
The frame may be made of aluminium.
There are two holes, one of which has been repaired with tape.
Shoji paper(white Washi paper) is applied to the back of the wooden frame in the first photo.
It is very nice if you can put paper over the stencil to let the light in from the back, or if you can see natural greenery beyond the stencil.
If the dye can be washed away with water, it can actually be dyed, I think.
