We didn't follow the instructions exactly, especially about drawing the right vertical line. We just lined up with the corners of the wall. Was a little time consuming, but unavoidable I guess. Originally, our wall was textured, so we had to put joint compound the flatten it out. Then we sanded. Then we put primer. This helped a lot for the wallpaper to adhere best. But, in the end, it came out super nice. It looks very good. We are very pleased. Looks very beautiful. It really takes two people. Don't do it alone. It was very difficult even for two people.
