If you your work involves meeting a lot of people, you might have a few, or lot of business cards. If not, you have friends who do. I saw this on a website where the owner of hundreds of business cards had the brilliant idea that instead of throwing them away, he would decorate his office walls with them. As single cards, there’s not much of a decorating accessory, but as you stack up a few types and colors, they can become a great brick for a mosaic on your wall. The method is up to you, make a pattern, form an image or just stack them up randomly. With a little planning and persistence you could end up with a neat office wall to look at, instead of the boring blank one you have now. If you don’t want to ruin the wall it is advisable to stick them on a huge cardboard which you hang on the wall like a painting. But it is entirely up to you. Just make sure you get lots of colors, as the most usual business cards are white.
