This was woven at my family's home, which used to be in the textile business. I believe it's cotton, but there might be a bit of synthetic fiber mixed in. I haven't measured it precisely, but there's about 30 meters. Please use it for handmade projects, remaking clothes, etc. It's an old item. There may be age-related deterioration that I can't assess, such as color changes, and I may have missed something during my amateur inspection. Please understand this before purchasing. To pack it compactly, I will fold it for shipping. Thank you for your understanding.
