Using these curtains is a breeze. First, decide whether you want the grommet top or hook style and let us know. Then, install them in your desired location. They'll immediately start blocking out strong sunlight and adding elegance to your room. When it's time to clean, you can either use a machine or wash them by hand. Just make sure the water temperature is below 90℉ to protect your hands. Take the curtains off gently to avoid any injury. Remember, each set has two panels. If you order a specific size, each panel will be half the width of the set. Also, be aware that there might be a slight color difference due to monitor settings. And if you want a custom size, it's easy - just select 'Custom Size' and enter the dimensions you need. Due to different measuring methods, a small measurement difference of +/- 3cm is normal.
