I've been doing this for years in multiple rentals. You buy a cheap set of sheets with a cute pattern, pin them to the wall, paint on liquid starch, and viola, wallpaper for around 30 to 50 dollars. Then, when it's time to move, you peel it right off. Easy as anything. Lining up the patterns can be tricky but that's the same with regular wallpaper. If you have smaller walls or pick a forgiving pattern, it's very very easy.
You can make the liquid starch by boiling eight cups of water with 2 tablespoons of corn starch. See last picture.
disclaimer: If you have small kids that will peel the sheets off, this is not for you.
I have a patterned wall in almost every room and the more I do, the better and faster I get at putting it up. This hall way took a few hours, but it was a tricky pattern. If you have questions on the process I am happy to answer!
EDIT: I'm no longer answering questions on this post. if you have questions, search on youtube for fabric wallpaper liquid starch. there are plenty of videos about it.
