Falling asleep with my finger on the screen of the Sketchbook app on my phone. I’d chose a smudge and soft pastel app. I started with an image in mind, but I woke up from my doze a few times and saw the straggly pattern developing! I could have worked on it but just let the ‘process’ carry on.

It is entirely random and I can alter angles and colours and opacity if I want to. But I like the idea of having no volition over it, making it really random.
