These curtains are really easy to use. Just install them in your living room where you want to block sunlight or add a decorative touch. When it's time to clean them, you can either use a washing machine or wash them by hand. If you choose to hand - wash, make sure the water temperature is below 90℉ so you don't burn your hands. When taking them off the rod, do it gently to avoid any accidents. Remember, each set comes with two panels. If the overall size is 118 inches wide by 106 inches long, each panel is half the width. Also, the color on your screen might be a bit different from the actual curtain. You can customize the size of the curtain by choosing the 'Custom Size' option and entering your desired dimensions. And you can pick between grommet top or hook processing for the curtain hanging. Just leave a message to tell us what you want. A small measurement difference of +/- 3cm is normal, so don't worry about it.
