Wallpapers are wall coverings, but they can also decorative works of art. Scenic wallpapers can span multiple walls and make a massive statement. Reproductions of the hand-painted originals are available from companies like Zuber, but they are both permanent and expensive. What about renters who want the look without the price tag and commitment?
Furniture: Above, Megan Pflug transformed this entryway credenza using a custom image printed large-scale that she then adhered onto the front. Megan chose her own image but Walls Republic has a selection to choose from, like the Italian landscape in the lead image above. Since you have to use paste with this product, it's good for decoupaging projects. Don't use it on walls!
It looks especially good on a tall cabinet. This one is just an IKEA wardrobe and some wallpaper, seen on Elle Espana.
Room Divider & Cabinetry: Kestie Lane and Hana Hakim, of Studio You Me, designed this Australian coffee shop called The Kettle Black (via Yellowtrace). They used black and white landscape images on both a room divider and on vanity cabinets in the bathroom.
Anewall has a great line of vintage scenes, including this shaded landscape which covers a 9' x 11.5' area. It's also removable and repositionable, making it great for built-in cabinets or even walls. Just peel it off when you move out.
Doors & Closet Panels: Brooke of Patina Farm covered these door panels in her living room with Gracie wallpaper — they hide the television when it's not in use. You could do something similar with bi-fold closet doors or a sliding barn door however.
Tempaper has a new Chinoiserie collection of self-adhesive, removable wallpaper that channel's deGournay designs, like the mural above. Designs are scalable to size, so you can customize the paper to fit your particular space.
Artwork: One Kings Lane shared this art print, which was hung in about 15 minutes using gold thumbtacks evenly spaced around the edges. Print out a black and white image as an engineering print at your local copy shop and you're good to go.
