So I was gonna write this up, but decided that as I had already recorded the entire process I would just direct you to the link for Soot & Whitewash episode 42.
Apologies if you prefer to read rather than listen, but typing it up I’d be bound to miss something, and writing comes quite hard to me.
The show can be found at:
Or anywhere that you would normally get your podcasts from.
I’ll just say now that it took a lot of thinking and time (relative to how I normally work) to make one (dull) image.
