Step seven of the snowflake method cycles back to characters and create full fledged character charts for each character. I actually flip-flopped this step and step five when I snowflake. I did the charts first, then did the one-page synopsis of their version of events. But that’s just me.
There are a ton of character charts you can download to give templates. The important things to remember to include history, motivation, goal, and how the character will change by the end of the novel. Some of those you should have from step three, but this is your chance to expand. All the appearance stuff is going to vary based on the author. You can get as in depth or shallow as you like. I tend to hit hair, eye, and skin color, build, and distinguishing features. I also do habits, mannerism, and personality. These descriptors help me to say consistent and help me see the character.
Here’s an example of a character chart from the third book in the Aphrodite trilogy. I’m leaving off the history, motivation, ect to avoid spoilers. Those would be in paragraph form.
Rocking on her feet, pushing her hair behind her ears, biting her lip, twirling
Hades, her friends, doctor who, anime, plant life. She doesn’t like horror movies,
getting sweaty, getting talked down to, or being in the dark.
The main template comes from Belinda Crawford here: http://belindacrawford.com/2012/12/27/5-more-scrivener-templates/
I made some adjustments to the character sheet, which you can check out here. Character Sketch
