I like these curtains for the price but they are still polyester. They have a texture to them so they are not a plain white. They came with clip rings so that was also a plus. The blackout really works and keeps the heat of the sun out. I hung them 6” from the edge of the windows to further keep the sun out. The clip rings are metal, not plastic so they slide easily on the curtain rods. They could use an iron or steamer which I have not done yet in the pictures.
