The brainchild of Timothy Travis, the Unitarian Universalist Ribbon is both simple to make and invokes powerful symbolism, as noted below.

Red, white, and blue united. Red for love of the physical, white
for love of the intellect, and blue for the freedom to express them.

Quality of life and humanist ethics,
free from faith and belief in myths,
miracles, and supernatural beings.

(Timothy Travis)

 

This ribbon can be made by tying a single knot in an appropriate piece of red, white, and blue ribbon, then flattening it.
