It really helps prevent many mistakes if you have a scale drawing
instead of a picture in your head. ;~)

This. I always sketch out what I'm planning to do, with
dimensions, before I start. Pencil and paper, because
I'm old-school. And generally not a true scale drawing
(I could do that, I worked as a draftsman a long time
ago), since I find as long as I work out and record all
the dimensions, I don't need it to be scale.
