I have 5 meters of black plain cotton fabric (Shinmosu). However, there is some discoloration. The most noticeable discoloration is in the third photo. The back side of this area has less discoloration. In addition, there is some discoloration on the edges of the fabric. How about using it for lining, etc.? - Color: Black - Material: Cotton - Type: Plain - Fabric Width: 36cm - Length: 5m Thank you for looking.
