Attention After unpacking the product, it is essential to iron the fabric at the first use to remove any wrinkles otherwise the effect of the black background becomes a checkerboard folds not very aesthetic! You can delete them by retouching software but it's better when you can avoid this. You can also play on the cursor levels of the image to blur a little creases. If you install the fabric on a support at a window, picture window, the black background is not usable because you see through. It must be installed behind a wall or even when placing an opaque black plastic behind the fabric. Only after all these points you can then take full advantage of the black background which fills its role properly. It will take care to store the fabric without creases otherwise it will stand the iron and it is a large area!
