I’m in love with this wallpaper! I put it up about 6 months ago, and haven’t had any major issues. I put it directly over very old wall paper, as well as over a painted wall and it’s held nicely on both. The pattern was easy to line up, and even where I wasn’t perfect it is very hard to tell unless you’re looking for it. I’ve gotten so many compliments, and plan to use it on one wall in our half bath as well! It has completely transformed our sad, old bathroom. I put it up myself, and it is not too hardkind of fun once you get the hang of it.
