Like anything, if you keep thinking about something then you should possibly use it or in this case draw on it!
I first saw this wallpaper "Frames" by UK artists Chris Taylor & Craig Wood a few years ago and I must say that it's never left me. You can then understand my inner joy when I found out New Zealand Wallpaper aficionados, Paperroom stocked it. Yay.
This wallpaper is the super-combo. You could leave it blank (with the black on white) or you could cut loose with the crayolla and go nuts - adults and children alike!
Workrooms, bedrooms, or even the loo would be be perfect for this wallpaper.
