Lately my hands have been itchy to draw. The other evening it began with the desire to draw a sunflower. Instead of drawing an imaginary one, I got off the couch and went and plucked a wilted sunflower from a two-week bouquet in the kitchen. I checked out the flower's structure, counted its petals, and took a good long hard look at it.
I sketched a sunflower head with 32 petals (more or less, I lost count in the 20s), shaded in the petals with colored pencils, didn't like the result, and went searching for the crayons. Before I knew it the sunflower got a stem and leaves. . .and a setting!
