It's an unusual concept, but it could be very interesting if done right.
I have one example of our project in San Clemente where our client wrapped wallpaper up the wall and across the ceiling and I have to admit that I like it even though I would probably never have suggested it to her.........
It looks great and I would now consider doing it without too much coercion...

I have been wanting something on my ceiling for years! We are finally buying, so i will be able to. I think going wallpaper is a great idea. We will have a trey ceiling, so i am considering chevron, i cant get enough of chevron. good luck, hope to see photos!

Hello,
I've done it in several projects and it has turned out wonderfully. You might want to try taping up a yard sample of the wallpaper you want on your ceiling and try living with it before you do the whole ceiling.

I agree, if done right it would look stunning, but please choose carefully, you can mess it up too.

I used anaglypta wallpaper to hide a cracked ceiling. Worked wonders.

It looks amazing as Long as I don't have to be the one to remove it! I just removed 30-year old wallpaper from a bathroom ceiling and swore I would never wallpaper a ceiling. Of course, today's wallpaper would come off a lot easier :)
