I'm in love with this wallpaper as an accent wall in my living room entry. It wasn't easy to line up the pattern and we found the paper on the outer part of the roll installed easily but the paper in the tighter/center part of the roll was impossible to lay flat and kept bubbling. We decide to pull it off and put those sections in less prominemt areas. Ideally the manufacturers would add a cardboard tube to the center of the role. Both of our rolls also has a printing line down the design that I noticed as soon as I removed the packaging. Luckily this purifying imperfection wasn't terribly noticable unless you looked closely. As others mentioned, the blue comes off on your hands during installation. Even with these imperfections, I'm in love with the look and would recommend to my friends with full disclosure.
