These three pictures of my lunchbox are some of the best contours and cross hatching I’ve done for class so far.
For the contour drawing in the top left corner, I began by drawing the lunchbox without lifting my pencil. I don’t remember using any under drawings for this one. For the other two, however, I believe I did begin by drawing two rectangular prisms stacked on top of one another.
The cross contour drawing was the most difficult for me because it was hard to visualize the dips and rises in the fabric on a grid. If I were to draw this over again, I might spend a bit more time on the cross contour to make sure I have the topography correct.
