I’ve done morning coffee drawings and afternoon tea drawings. Now I do the occasional dog walk drawing, for those occasions when walking the dog involves a lot of waiting (if you know what I mean).
The advantage of the dog walk drawing is its devil-may-care aspect. You can feel free to put whatever you want down on the page because “what does it matter?” I like that — as I like all things that wend toward immediacy in art.
You just draw various scenes that happen upon your gaze as you wait for the dog.
And sometimes you even draw the dog.
