We purchased fuchsia for our daughters room and they are gorgeous! No defects, delivered in clear bags with a tag. I washed and dried them according to the tag to get the wrinkles (creases) out. I would say they score a five on a one to ten light blocking scale, where one is sheer and ten is completely light blocking. If you want the colors and textures of these curtains with complete light blocking, you could pair them with an ultra thin white light blocking curtain which I might do in the future! I guess if your really crafty you could sew a fix as well.
