Vintage sheer synthetic organdy or organza fabric, nylon or a blend, with a flocked pin dotted pattern like dotted swiss. It's 44" wide x 5 yards.
It's showing more than a single layer in the first photo... this is crisp and very sheer, a peachy coral color. Looks nice (but bare!) over skin for summer sewing, or would make pretty lampshades or curtains to give a warm glow to the light.
