I applied the Botanical Terracotta Gato Garden Novelty Peel and Stick Wallpaper in an anteroom converted to a kitty-safe space for a new cat coming to our home. I am experienced with peel-and-stick installations and have used similar materials many times. The end result was fine, though I had to do some patching and fixes to make it work. Problems included stretching that made the patterns misalign and backing that did not peel off easily.
The stretching happened because I applied the wallcovering to a wall with about a 30-degree bend in it. The wall was imperfect, and fitting the material to the contours resulted in stretching that distorted the wallcovering. While some of the pattern lined up perfectly, I had about a quarter-inch offset at the bottom. Since I am experienced, I sliced the wallcovering to relieve bunching and crumpling, then cut small pieces to patch areas not covered or to provide the illusion of match for the large elements of the design.
The more problematic issue was backing that did not peel off. It stuck in places, tore and left a thin layer of paper that I had to carefully scrape from the partially installed wallcovering. This was a tedious, time-consuming, and frustrating process that further distorted the vinyl wall sheet and even caused a small hole in one place. I don't know if this was a glue issue or a paper issue, but it was a huge irritant.
Overall, I am pleased with the end result, but had I ben a beginner, I might have given up. I would have been more pleased if the wallcovering were actually a paper or woven fabric. It is vinyl, like a drawer liner. I would use the product again, but I would cut it on the transition for all corners, including those that are less than 90-degree corners.
