Using these curtains is a breeze. Just use the free hooks to hang them up where you want. They'll instantly add a touch of style to your room and block out the sun. When it comes to washing, make sure to separate them based on color to avoid color bleeding. You can machine wash them in cold water on a gentle cycle, but don't let the water get warmer than 30°C. Don't worry about the ±3 cm size error; it won't stop them from fitting well. And keep in mind that the color on your screen might be a bit different from the real curtains. Each set comes with two panels, so you can dress up your windows beautifully.
