I gave two classes this week on sketching. One was with a smaller group of 5 at St. Joes and the other my Architecture 415 summer class a larger group of 18 students. Both are great in their own ways. It is interesting teaching non-architects vs. the architecture student. It challenges my skills in teaching perspective to people who might not have otherwise been exposed to these ideas. Teaching architecture students is more fine tuning them and if they aren't getting it...helping them see a view more clearly and understand the underlying structure of a sketch.
