Wallpaper...you're starting to grow on me

Wallpaper is just one of those things that makes people cringe, myself included. But lately it seems to be making a comeback and I'm actually becoming a fan of it. It really spruces up hallways, entryways, and small rooms, but I think it also looks pretty charming for a living or dining room.
