if Building From Plans is called Scratch Building, then what is it called when you draw the set of plans as well as build from them? Or crayon on a napkin a profile & build without a "Set Of Plans", cut a rib freehand & just make the others by stack sanding, is that Scratch= like Building From Plans?

I fry up some sausage, toss in some flour, then some milk (sometimes the goat didn't give as much as I wanted) and pepper it into Gravy. No Recipe, just eyeball everything. Some people add sausage & water to a packet of graveymix & call it scratch cause they fried the sausage & didn't open a can.
