Eclipse Zana Trellis Fashion Blackout Curtain Panel

Not heavy, dark enough to watch movie in daytime. Pros: 1): one panel is about 1 lb; it is not heavy as my other light block curtains. It is very easy to put on/take off, and no heavy rod needed to support it. Any curtain rod will do the job. 2): It blocks most of the light from the sky, on a sunny day I can watch movies without any problem, not loosing details in scenes. It is impossible for me to measure how much percentage of sun light it blocked; I would say almost all of them. 3): Also dark enough for a nap. But I would not suggest using it for little kids for this purpose. The darkness may keep them sleep in the day, and you will have some hard time in the night to put them in the bed. 4): The fabric has a smooth surface. This is important for me, not to trap too much dirt. Living in a area close to coal burning power plant, dirt in the air always a problem. 5): Machine washable and almost dry when taking out of the washer. Just line dry it on the curtain rod (yeah, a little lazy here). Other thoughts: 1): Summer is coming, and when uses it with open window, I put some weight at bottom to keep it stay.
