In my Crealde Urban Sketching course we tend to take one class to sketch fellow students as they work. I do quick 5 minute sketches to demonstrate how to position a figure on the page. This particular sketch seems to be a sketch on top pf a sketch. I forget what I was demonstrating with the rough grid pattern. I was probably stressing how to avoid lining everything up on a grid and avoid horizontal and vertical lines.
Most classes are outside exploring the campus with our sketchbooks. I do this because it keeps my students safer during the pandemic. I was advised to offer an advanced urban sketching course but not enough students signed up so it was scrapped. No artist thinks of themselves as intermediate or advanced. Heck every one on my sketches is a series of mistakes.
The next series of Crealde Urban Sketching classes is starting up January 20, 2022. We meet on Sundays from 9:30am to 12:30pm.
