Read through pretty quickly, taking notes. Trying to learn more about drafting as I enter my woodworking era. Hand-lettered and illustrated, it's a very nice, well-organized, concise, interesting book. I skipped all of the stuff on perspective, which occupies most of the text in the book, because it's too technical / beyond what I need. But otherwise feel like I learned lots.
