5 Principles of Flag Design
There are five basic principles of flag design according to the North American Vexillological (Vex-il-lol-logical. That extra 'lol' makes it sound weird) Association. Vexillology is the study of flags.
#1: Keep it simple
The flag should be so simple that a child can draw it from memory.
Before I moved to Chicago, in 2005, I didn't even know cities had their own flags. "Most larger cities have flags." That's Ted K., flag expert, totally awesome guy. "I'm the editor of a scholarly journal on flags called 'Raven: A Journal of Vexillology.'" And that first city flag I discovered in Chicago is a beaut: a white field, two light blue horizontal stripes, and four six-pointed red stars across the middle.
#2: Use meaningful symbolism
In the Chicago flag, the blue stripes represent the water, the lake, and the rivers. The red stars represent significant events in Chicago's history.
