Forgiving for beginners.  This was my first time ever wallpapering so I went with an adhesive to not over complicated things. It was easy to do once I got in the hang of it but is still a 2 person job. You definitely want to buy the right tools to cut it and smooth out air bubbles.  I’m very happy with how it turned out.  Not sure if I’d do it again though.  Might go with a regular cheaper paper and hire someone to put it up.
