This project is always a student favorite. At this point in Drawing 1, students have been introduced to shading with graphite. Yesterday, we moved onto ink and did some general practice shading with markers using hatching, cross-hatching, and stippling techniques. In this project we focus on using hatching to make shapes appear three-dimensional. Students start by drawing the tubes and then some guidelines that will help them stay on track as they add ink.
In the top right image, you can see the guidelines I have students add before they start adding any hatching with ink.
