Turning old items into art is a creative exercise that is also environmentally friendly. Items like wrought iron, wood, plastic, fabric or just about anything you can think of can be upcycled. Moreover upcycling glass bottles for painting, or to be used as a vase for plants is very common. Therefore USP is, nobody else will have the same decor as you do! Also to accent the space, consider backlighting the piece with LED lights for depth.
