Wallpaper is BACK!

Wallpaper is definitely back, and we don't think it'll be going anywhere anytime soon. We're sure there's at least one person out there who's cringing right now, but don't worry - the wallpapers we're seeing today are certainly not the wallpapers you remember from your grandmother's house. Many of the best new papers are designed and produced by small firms, and are a great way to bring some pattern and color into your home
I've fallen in love with the bold patterns of wallpaper from the 1970s—and the modern interpretations of them. But unlike the pattern overload of the 70s, vivid wallpaper is now used in smaller doses. Try papering just one wall, a closet door, the back of a bookshelf, or the front of a modern buffet. Hang a poster-size sheet of it or frame smaller pieces grouped together.
Finding good wallpaper can be a challenge, so here are a few great online wallpaper sources:

American Blinds has a smaller selection of good retro wallpaper, 
Interior 1900 has the real stuff your grandparents might have hung on their walls. It's pricey, and quantities are limited. A good source for authentic 70s wallpaper.

Graham & Brown has an extensive collection of up-and-coming wallpaper along with 70s-inspired patterns.

Wallpaper from the 70s is my favorite site. It's based in Germany, but they ship anywhere—and they promptly answer emails. Best selection online that I've found.
