We’ve said it before and we’ll say it again: as much as we love the look of modern design, we LOVE when it’s a design that uses old things to make new things…that’s sustainable and smart. Austin, Texas furniture company Petrified Design is grabbing up old but still usable building materials and shaping them into pretty darn good-looking pieces of furniture. Composed of designers Tyson Pendergrass and Gable Bostic, you can read all about them on a recent feature in Austin CultureMap. Check them out on Etsy. And their website.
