Vintage Japanese Stencil Flowers Leaves Kimono Katagami in Showa Period http://www.etsy.com/listing/92268437/vintage-japanese-stencil-flowers-leaves
This was an amazing find. This is called "型紙" or "katagami" stencil. This is a stencil that was used to make "kashigata" (for more information on "kashigata please see below).
They are from the "昭和" "showa period" . The "showa" period is from 1926-1989 but these are at about 25-30 years old .
Katagami are made of multiple layers of thin mulberry paper which are bonded with a glue extracted from persimmon, which makes a strong flexible brown coloured paper.
This katagami was used for "katazome" which is the method of dyeing fabrics (kimonos) using a stencil and a resist paste. The resist paste was made with rice flour and when dyed, the dye didn't adhere to the areas covered with the paste. It was an inexpensive way to make all-over patterns similar to a woven cloth.
