Using your 3D blackout curtain is easy. Just hang the two panels up in your living room or bedroom using the free hooks provided. For maximum blackout and noise - reducing effects, make sure the panels cover the window fully. When it comes to cleaning, you can gently machine - wash the curtain in cold water. Avoid using bleach as it may damage the fabric. And remember, because of monitor settings, the color you see on your screen might be a bit different from the real curtain.
