This drawing is to be completed in your sketchbook. In a 4 x 5 in. format, using graphite pencils, draw a "continuous field" composition of an actual texture. Your image should be similar to the one above in that there is no reference to the exterior shape of the object, only the texture zoomed in to fill the rectangular format. A "continuous field" composition touches all sides of the format. Bare in mind that "texture" drawings are essentially "value" drawings. Pay close attention to contrast and gradations. It will help to set up a strong, single directional light source.
