On the very softest of pure cottons (India is the only country in the world that makes this very fine, very soft cotton!)
Images are on both sides. I have had it for many decades (purchased when I lived in Asia back in the 70's/80's.) The size is about 68" wide by 40" ~ rectangular piece. I just hand washed it and hung it in the sun to dry so super clean. Please note I did do some minor hand sewing repair on one small edge of it. Photo of that included. Photos are from both sides. Faded, muted soft colors. Has been in my home since then. Non-smoking/pet-free home. Not bought at a flea market yesterday ~ I have sewn 'loops' on both sides of the top for easy hanging.
