Update after professional installation:

Despite following the instructions and having it installed by a wallpaper specialist with 40 years of experience, after 2 weeks on the wall, this paper is starting to lift on every single edge. I am so disappointed bc the paper itself is Gorgeous. The bathroom has not been used since we installed as I am waiting on vanity and toilet to come in. At this rate,  I am at a total loss at what to do. Such an expense for this paper and installation and I think it’s going to end up off the wall and in the garbage  ‍♀️
