When looking at these close up, it’s easier to see that I’m not really a fan of filling in spaces. I get distracted and the pen goes outside the lines as in the stairstep one, or I don’t completely fill up the black space, like the one on the right.
It’s not so visible in real-size though.
When in doubt, use tipple! That’s the tiny circles on the top on this one.
It reminds me of that Mr. Rogers (I think) segment where they filled the jar with marbles and then sand and then water to show that when you think something is full, it’s not. (Quick googling to see if I could find the segment has told me that this has become a priority metaphor. Which, fine.)
