The most important thing is to apply the wallpaper carefully! Start https://tapeko.us/catalog-wall-murals/nature-wall-murals/ at the top and slowly move down, smoothing with a rubber spatula or soft cloth. In the case of self-adhesive wallpaper, the protective layer should be peeled off gradually, without pressing too hard, until it is in the right place. You can push small air bubbles out towards the edges. In the case of larger air bubbles, you can make a small hole with a fine needle and gently release the air. With a little patience and precision, the effect will be beautiful!
