One Breath, One Line
Let a single comfortable exhale set the length of a drawn line.

Time: 1–3 minutes
Use an ordinary pen and paper. This is a mark-making experiment, with no need to change or slow your breathing.
What you need
- paper
- pen
Try this idea
- Rest your paper and forearm comfortably, then place the pen anywhere on the page.
- During one ordinary exhale, move the pen gently in any direction. Lift it when you naturally finish breathing out.
- Leave the line unchanged. Stop there or make up to two more lines, allowing normal breaths between them.
A smaller version
Make one short line at any pace, without coordinating it with breathing.
A good place to stop
One untouched line is the finished work.
Make it work for you
Skip the breathing cue if it is uncomfortable; move the pen for a moment and stop. Use a broad, loose movement rather than tiny marks.
Another way in
Repeat on another day and notice how the lines differ.
