I feel like I've fallen down the rabbit hole every time I visit Walnut Wallpaper. Their featured designs, by underground artist Geoff McFetridge (below), are just the kind of fun patterns my friends and I squeal over!
The best part? It looks straight out of the vintage stores we frequent downtown, but the line is produced using only water based ink, with no chemical waterproofing (I'm guessing with the similar-style vintage wall papers - that would not be the case!).
Since wallpapering a whole wall for me is definitely scary, I would scour goodwill for different size frames, spray paint them all black (or all white) then create a wall collage with all the different styles... wallpaper without paste!
Also, if you browse by style, be sure to click on the Eco-Friendly and Femme Fatale styles. You could save some $$$ by ordering just a bit and wallpapering a wooden panel to use as a creative art solution. Maybe three, since grouping adds more impact? Ooo, brainstorm! I could use it in the center of the collage I've been thinking about...
