I need some help applying wallpaper in my en-suite bathroom. I recently purchased this product: https://peelandpaper.co.uk/products/audrey-pinstripe-wallpaper in the “Peel & Stick Vinyl” as it was recommended by a friend for being the best moisture resistant/satin sheen product if wanting wall paper in a bathroom. I know it should be fairly straight forward and it’s a literal peel & stick, but I want the best possible result & i’ve never done anything like that before so any assistance would be greatly appreciated.
