We looked 3 stained glass windows by Lightworks in England. I asked the classes if these designs looked 3d like the landscapes they had just completed or if they looked different- flatter. I asked them what kind of lines they saw and what kind of line they did not see a lot of.
We also quickly talked about the use of tints and shades and how you you create them in a drawing.
The students had used tints in the landscape drawing they just completed, and some students had made shades of colors to create shadows in their drawings.
I emphasized that even though the new drawing would look a lot different then the landscape, the students would be using some of the same technical skills. Plus, both drawings used a heavy dose of contour lines to outline the shapes, no matter whether those shapes looked 3d or flat.
Students drew 5 vertical lines first- each one a different length than the others.
Next they added color using one of 3 color families- I threw in a quick introduction to analogous colors too.
The final step was to use a black crayon to trace their contour lines.
Bada bing, bada boom.
