I found this fabric in Tokyo back in July. at first I thought it was just a piece of indigo dyed cotton, but after picking it up and noticing the texture and light weight I inspected it closer and found that it has a cotton warp and a paper weft. The fabric must date to around the early 20th century.
Above you can clearly see the paper weft threads in one of the ragged ends of the fabric. Below I placed a skein of my handmade paper thread next to the fabric.
While visiting Kyoto I went to Gallery Kei, the gallery had recently exhibited a huge collection of antique paper fabrics. Below is a link to the exhibit at Gallery Kei and some photos of the interior of this beautiful shop. http://gallerykei.jp/event-index.html
