We have a wall in our living room that is really hard, we can't get nails into it, hence no art. I think there might be concrete underneath some thin layer of something or other. Now, wouldn't it be nice if I could get my hands on this concrete wall paper from Norwegian designer Tom Haga? My concrete wall could actually live up to its reputation. Remember the scrap wood wallpaper by Danish designer Piet Hein Eek I wrote about last year? No need to get an industrial loft - paper your condo to look like one - or perhaps a forest, or the view from the moon.
