Imagine this, wallpaper has become friendlier. If you've read some of my other articles and blogs you'll know that I have a bit of an ongoing battle with wallpaper. It's horrible to remove and can damage the wall underneath. I actually have no problem with the way it looks.
So, if you're going to go the wallpaper route at home, please opt for strippable paper. This paper is designed with the knowledge that someday it's probably going to be removed, so it comes off the wall much easier. In fact, in theory you can grab one corner of it and begin peeling it right down, quickly and easily. Of course nothing really ever goes that smoothly, but its sure a lot easier than the old fashioned stuff which requires a scraper, steamer, knife, a caustic removing agent, rags, buckets of water, sometimes dry wall compound and an unbelievable amount of patience.
If you're going to apply strippable paper, be a little wary of brands that recommend you use additional paste. The extra paste makes it a bit harder to remove, in fact I fear it may end up as difficult to remove as traditional paper. You also may not have the longevity of traditional paper, but that may be a good thing.
As a side note, make sure you get a durable wallpaper that's scrubbable as well. You want a wallpaper you can clean without worrying about damaging.
