Whether working on canvas or paper, Edda Renouf cuts into her material with a metal etching tool. The incisions, as seen in these works, usually conform to a grid or other geometric form. This structure is not entirely logical, however, as the artist uses what she calls an intuitive sense and not a mathematical formula to determine the exact placement of her marks. In this way Renouf explores the complex variability of all so-called systems. In some works Renouf uses graphite or pastels rubbed over the paper, thereby highlighting the incisions and the details of the paper itself.
