Wallpaper.....I adore the stuff (although have to admit I could never actually put my own up). Generally I particularly love a bold pattern and colour used on an accent wall. It transforms a space so dramatically and there is no shortage of choice out there to fit every taste.
It took me a good 6 months of looking at swatches and shopping around before I found the perfect paper for my bedroom, but the result turned out perfectly. Naturally I wanted pink, and this paper has a rich dusky pink that is bright enough but not over the top (in my book anyway. Black and silver roses give it a touch of the vintage I love. It is a huge wall so most certainly makes an impact.
Here are some more I would definitely consider, for a new look....
