1. Yeah, you can use a ruler.

  2. Ballpoints are more forgiving, and so from lesson 6 onwards I feel that students will have learned plenty from the use of their fineliners, and with the increased complexity of these last lessons/challenges, I want them focusing more on the content of the lesson rather than the confidence of their linework.wa

  3. Yes, as explained in Lesson 0 (it's part of the rules you follow from getting official critiques). Generally when students are overly eager to jump straight into the next lesson, it usually implies that they haven't been following the 50% rule.

  4. Explore different kinds/styles of wheels.
