What is the best method to wallpaper with newspaper?

I did that once in a den. It wasn't that bad and I actually liked the yellowing and worked it into the color scheme. Basically, just use a pair of sponge rollers. One to roll the wallpaper paste on the walls (I used that so that it was easier to strip later), and the second to smooth the paper after I put it up. Then after it dries overnight, go over it with a a clear urethane to seal it. Use one of those sponge rollers to put it on without bubbles. Regular clear urethane will yellow a little on its own as it dries, so you get a really nice effect. And also, because urethane will seal it, you'll be able to wash it with warm water and vinegar to clean any marks or stains on it later.

I'll admit one thing after doing it. I thought I really had a whole lot of paper...but it was deceptive because of the overlaps. So we ended up doing a border above and a wainscoting below that we just painted an antique creamy yellow with an antique white trim. It was sweet, especially for a den.

C'mon, it really IS tacky and so cheap looking, not at all professional! Would be much better to frame some good pages in poster frames and hang them. Milk paint is cheap if you're on that low of a budget and would be a very quaint backdrop for the newspaper posters. Try this recipe...
