Looking at all of this together brings Wile E. Coyote to mind.  

These are most of my notes, sketches, calculations, math, and missteps.  I use a bunch of different methods when I'm planning out crochet, depending on the feature I'm thinking about.

It's all sorta written in the moment.  If I try to come back to this months from now, I might have no idea what I meant.  I'll get it all written more clearly soon.
