Cassandra Tondo calls her work "art with a conscience." The Southern California artist uses fallen leaves and leftover house paint to beautiful, subtle effect. Her love of nature is something I can definitely get behind—especially when the results are so pretty on their own terms. And she works in a variety of styles and price points: paintings, prints, even cards. I like them all; the eco prints, made using fallen leaves found on neighborhood walks (see above and the bottom two below), might be my favorite.
