Using these curtains is easy. Just install them in your living room, and they'll block the strong sunlight for you. When it's time to clean, you can either use a machine or wash them by hand. For hand - washing, remember to use water below 90℉ so you don't burn your hands. When taking the curtains off for washing, be gentle to avoid getting hurt. Each set comes with two panels, so if you need a specific size, you can customize it. Just choose the 'Custom Size' option and put in the size you want. Also, note that the color on your screen might be a bit different from the actual curtain because of monitor settings. And don't worry about small measurement differences, as an error of +/- 3cm is normal. You can also choose between grommet top and hook processing. Just leave us a message to let us know your choice.
