This wall treatment using vintage recipe cards in the kitchen of a Providence art space reminds us of Depression-Era interiors where newspapers were often used as wallpaper. While the results might not be beautiful in a conventional sense, they show that you can be creative about your surroundings no matter what your economic circumstances.
It's an excellent idea for re-using and displaying paper ephemera in a witty way. We're not sure exactly how these recipe cards were adhered to the wall, but you can make wallpaper out of anything from newspapers and magazines to color copies by applying them to the wall with polyurethane (one coat underneath and one on top to seal the paper).
