This crisp, tightly woven cotton has a small print in almost-black indigo, other lighter blues, and white. It will probably soften with washing. It's traditional yukata weight and weave, which is very similar to quilting cotton and meant for warm weather kimono in Japan. On the back, the colors aren't quite as dark. 

13.5" wide.  Sold by the full yard and we'll cut yours in one piece from the perfect condition, never used bolt. This bolt is tightly woven, excellent quality, and seems to us new or fairly new, not vintage. 100% Cotton. Japan.
