"A lighthouse with eyelashes", that's wonderful, thank you - and for your whole comment. I explore with the notebook pieces because I'm not planning to share them - I work and re-work them, see where they go - about half end up worth posting.
I have a similar system of working out things. Exploration takes many shapes. I do small canvases, but it's the same concept. I find notebooks confining--don't know why, just the way it is. Must be the binding!
