Before you throw away your denim, send them over to Denimu and see what kind of artwork this talented individual can create from your worn-out jeans.
Denimu uses old jeans as a way to exercise his creative mind for his artwork. While blue is the dominant color, the artist does apply a bit of red to accentuate his portraits. Some of Denimu's work have a watercolor/painted appeal, with my personal favorite being the ones he gives a retro 50s pop-art aesthetic to. Check out his amazing artwork in the gallery.
