Using these curtains is a breeze. Just install them in your living room using the grommet top or the hook you've chosen. They'll do a great job of blocking sunlight and adding a decorative touch. When it's time to clean, you can either machine - wash or hand - wash them. But remember to use water below 90°F to protect your hands. Each set has two panels, so if you need a certain width, calculate based on each panel being half of the total width. Also, keep in mind that there might be a small color difference because of your monitor. If you want a custom size, just select the option and put in your measurements. And don't forget to tell us if you prefer grommet top or hook processing. Normal measurement differences of up to 3cm are okay, so don't worry too much about that.
