There are many artisans who have committed themselves to repurposing materials into art instead of letting die a horrific death in the landfill.
One such artisan is Marc Staples who is making wine racks from worn out horseshoes. As a designer and sculptor, Marc creates these pieces in his studio/workshop in Durham North Carolina. They are great functional gifts for the horse enthusiast and/or wine lover.

Making art and saving the planet at the same time is a day well spent.
