This paper is so so pretty, but we were laying it out getting ready to use, and realized there was some sort of critical production error with our batch. The print doesn't line up, and being a continuous geometric pattern, it's 100% unusable because it ruins the illusion. It would've looked like absolute trash on the wall, so we returned it.
We also purchased another print by this same manufacturer for a different room, which luckily did not have the same fatal flaw.
I can tell you from our experience with the successful print that its pretty easy to do with two people, a ladder, and a plastic drywall knife.
My biggest complaint was that it absolutely stinks. The vinyl smell is obnoxious, and I have such a huge headache from it. It says on the package it's certified for low emissions...but I said, "How?" If you have someone in the house with asthma or other breathing issue, you may want to ensure they're away for a few days or perhaps air out the wallpaper in another location.
