We've got one spot in our house where I decided to put together a budget "feature wall". I made the kind of flour paste used for paper mache and stuck the classified pages from The Weekly Times over it, plus a few newspaper cartoons. It looked good, particularly once the paper aged and yellowed a bit, but when we moved in our new rodent-proof steel cabinet pantry a few years ago, it had to go in front of it.
It won't be a permanent feature anyway, because the wall it was "improving" is the dreaded asbestos cement sheet. However, I may repeat the idea somewhere in the house where it can be a more long term thing.
