Today's drawing
No prompt is set for today yet. The canvas is always open.
Ten minutes a day beats an afternoon on Sunday
Drawing is a motor skill, and motor skills consolidate between sessions rather than during them. Short practice spread across days consistently outperforms the same total time in one sitting. That is the whole reason this site is built around one small thing a day instead of a course you have to survive.
Sixty seconds counts. If today is a bad day, do the warm-up and stop - that keeps the habit and the streak intact, which matters more than the drawing does.
