For the last several years, an eco friendly Leather eyewear line crops up, Butcher Couture Eyewear. Using leather as a medium, the look is sporty yet stylish and sustainable, using natural materials. From the little that you can read about it it is about fashion and sustainability. I believe they launched in 2009.
They have launched a website www.butcher-eyewear.com (coming soon) on Facebook as a group, (Butcher Couture Eyewear) and have a YouTube channel, which is the same as the website. Based on everything I have read, it looks great and can’t wait till they get up and running.
