I watched the first couple videos but stopped when they started a practical example (3rd video, I think). Turns out you need some basic tools I don't have (dividers, parallel rulers) and charting paper. They don't mention this upfront. I need to perform the steps they demonstrate in order to have it sink in so I stopped watching. The tutorial is interesting enough that I'll see if I can get the necessary things and pick it up again.
