I recently found this late Edo or early Meiji period obi made from hand spun cotton. The obi has been dyed using indigo over dyed with a yellow to create a green color. The pattern was created using a katagami or “stencil” to deposit rice paste onto the fabric before dying. The obi is made from two lengths of fabric sewn together in the middle. I think it was made this way because the person who made it was taking advantage of leftover fabric.
I love this geometric repeat pattern. I think it could really work as a modern textile. I would like to try to reproduce this fabric in the future. The colors that come out in this last photo show off the colors possible when over dying indigo.
