I think it really depends on the style and look that you want to achieve in your house - you should never give someone the advice to use wallpaper without knowing their design aesthetic. With that being said, I think that wallpaper is a lovely touch in older heritage listed home, because you can add the modern touch through it to the home, depending on the pattern.

I see wallpapered ceilings a bit in photos. See example. I can't imagine that would be easy to do! An application I did like was wallpaper between dark painted rafters. It was really effective. I don't envy the person who had to do that job. Or anyone who wants to remove it later. In my previous home, every room had been wallpapered sometime in the 80's. All bedrooms, hallway, living room, kitchen, bathroom, toilet. Quite a process to remove! I don't mind wallpaper but I didn't like the ones in that home. I think wallpaper can work really well in homes with a grander scale. High ceilings, architectural trims etc. In smaller homes, a restrained use is more appropriate IMO.

Hi Betty, There are lots of in between wall paper styles out there. We have a few examples of wallpaper feature walls (in a large room) or all walls (such as in a powder room). Here is the powder room link: https://www.houzz.com.au/photos/matilda-place-contemporary-powder-room-sydney-phvw-vp~92259318 I'll send through the other links in a few minutes. Hope these help to give you other ideas! Good luck. Cathy
