Cone Mills light shades of gray mid weight stretch denim, 3 yards (60" wide)

Very large piece of Cone Mills fabric, 3 yards + a few inches, 60" wide. Fabric is in excellent condition, I did locate one subtle smudge (probably just from handling/storage over the years) but see last photo w brass ring as marker. Assume fabric is a cotton blend (for stretch). #Haberdashery #SewingNotions #SewingFabric
