When I hear the word wallpaper I'm immediately drawn to a mental image of the 1970s. Something similar to, say, this? But, in reality, modern wallpaper is actually pretty cool. I've seen it used a bunch on HGTV so my opinion has really turned around. There's even a hilarious episode of Property Brothers where one woman is determined to use the world's busiest wallpaper (at whatever cost) much to the chagrin of both Jonathan and her husband.
