In my art class, there is a fake Red Delicious Apple. Sketching it gives me fits. It’s a dark object, so there are only four tones (6-10) that can be used, other than the tiny spot where the light hits it.

Mostly looks like the apple

My bright idea was to buy one, one with as many contours as possible, and sketch it at home.

The dreaded sketch object

For most of the time, in my sketch it looked like a bell pepper. I worked on it until I didn’t know what else to correct. That’s always my stopping point.
