This is a piece of fabric that has only been unstitched, and the creases remain. I believe it's cotton, but I'm not sure because there's no certification tag. Photo 4 is the back. It's dyed, so it's of medium thickness. I'm not sure if it's indigo-dyed because I haven't washed it. There's a storage odor like old dye, but there's no color fading or transfer. Please judge from the photos. 24 x 98 + 36.5 x 9 cm, 36.5 x 96 cm, 2 pieces each, There are 6 pieces of the small parts like in Photo 3. It will be shipped folded up small.
