Instead of a sheet of paper and a sharp pencil I use a mouse, a screen and photos I've made. A few blenders of different sizes (Photoshop and the likes), cooked to perfection before it is served here on a beautiful archival 400g museum quality paper. Sizes: 16"x16" and 16"x 18". Metric: 40cmx 40cm & 40cmx 46cm. Other sizes available upon request.
