"Snowflakes are amazing!" I gushed to the students in a recent "Words for Winter Wonder" writing workshop hosted by the Lake Superior Writers in Duluth, Minn.

Water vapor crystalizes around a piece of dust, or dirt, or even a unique bacterium. Then, as puffs and gales of wind toss the nascent snow crystal inside a cloud, they experience varied combinations of temperature and humidity. The crystal grows differently in each new habitat.

"Now, we get to try to imitate that beauty that comes with variety," I said as I passed out a different color of paper to each of the six students. How fitting, I thought, to have six students to imitate the six-sided snow crystals.
