Given that many of my clients share their homes with cats and dogs, I wanted to pass along this clever--and earth-friendly--pet bed idea from Kirsten Schueler, winner of Design Sponge's 2008 DIY contest. This is a great way to re-purpose a vintage suitcase. If you're a fan of the Ballard Designs look, consider creating one of these in a black, white, and pear green color scheme.
