In this video from the series How to Architect, Doug Patt demonstrates how to architect with the basic drafting tools for an architect when working by hand: a parallel rule, a t-square, and an Ames lettering guide to create the lines for the lettering.
Although this is a controlled tabletop activity, the principles apply to graphic recording. Doug's advice: "I'd say the most important thing to remember about hand lettering is that your letters need to seem animated while still appearing orderly and neat. I think this is achieved by using a few conventions."
