Take your time when hanging this wallpaper. Was very easy to put on.  Important to wash your walls as there is dust and cobwebs you cannot see.  Clean walls ensured I had good adhesion.  Be sure you take time to smooth paper with plastic edge to push out all air bubbles.  I changed cutting blades a couple of time which helped with clean cuts.  I love the peel and stick concept and no problems with the wallpaper staying on the wall.  I measured one, twice and sometimes a third time to ensure I did not waste wall paper.   There is a bit of wasted paper as there is a pattern to match.  I am very happy with the look of my front entry way.
