Because the pattern is so high impact, I think it works particularly well (as so artfully demonstrated above) as an accent wall or in a formal dining room, where dramatic walls somehow seem more appropriate. To break up all the pattern and to minimize costs, I would install the wallpaper below a chair rail and then paint the remainder of the wall in a coordinating shade of peacock blue (for a higher contrast, you could go with white, gray or even a completely contrasting color like chartreuse). I could also see this in a large walk-in closet -- the peacock blue would make you feel like you were getting dressed inside a lush jewelry box.
If you're a commitphobe or a renter, wallpaper can also be used in smaller, less permanent projects like framing smaller cuts as wall art or gluing remnants ontp storage boxes or containers as Anna did over at Door Sixteen:
Also, if you love Ferm Living's feather pattern, they also have it available (in the reverse colorway) in bedding. I actually think doing up a bedroom with both the Feather wallpaper and the Feather bedding would be a really bold move. Obviously it's matchy-matchy, but I think you can get away with that in a bedroom. While using coordinating wallpaper and fabric is very reminiscient of the 1980s -- a decade rapidly becoming en vogue again anyway -- the modern and graphic pattern would definitely keep the look updated.
What about everyone else? Do you love the idea of using wallpaper in your home or do you hate it? If you love it, what patterns are you drawn to?
