While an observer usually wants to include as much detail as possible in a sketch, the finished drawing can raise unrealistic expectations if the sketch is used to familiarize new observers with the object. This column describes the process of supplementing a detailed sketch with a simplified version that represents the at-a-glance view of an object. |
Suggested Sketching Materials: |
- White, acid free sketch paper
- HB and 2H graphite pencils
