This assignment was to find a soda can, crush it, and then stretch it back out a bit, so that an interesting pattern of wrinkles and shapes would be formed on the surface of the can (rather than drawing a plain ol’ cylinder). We were able to choose our media for this, so after refamiliarizing myself with colored pencils in the sketchbook assignment, I used them for this can also.
One note: the can, which my husband found for me since I don’t drink sodas, was a normal red Coke can. But my supply of red Prismacolors was too used-up to complete the drawing. I did have plenty of blues, though, so I used those and “translated” the colors and values.
