The first drawing of our dog Ruby was done with a Draughting #314 graphite pencil. It was drawn from a photo.
The second drawing of our cat Mr. Frodo was done very quickly, starting with a few gesture lines, followed by rapid shading, and finishing with line. I drew him from life as he was eating and I had to be quick because there was no telling how long he was going to remain in the pose. He moved just as I was getting to his food dish. Drawn with a 0.9mm mechanical pencil.
