Tree of Life Tree-free Eco Note Cards, 6"H x 4"W: Our eco-cards are handmade using a very special paper. This paper used to create these cards is not made from the wood of trees. Instead the "paper" is made of excess cotton fabric scraps. This cotton fiber is a renewable resource left behind by India's bustling textile industry. Handpainted with a Tree of Life design, the cards are blank inside. Handcrafted by our valued supply partners in India.
