White cotton lace. I purchased this item new and unused, but since it's vintage lace, I washed and ironed it once for use. I stored it without using it, so it's in beautiful condition and ready to use immediately. It looks clean to me, but there might be something I missed. Please understand. I was planning to use it for the scales of carp streamers (koinobori) or for the frills of curtains, etc. It's 6 meters long.
