The snowflake method is a way to design a novel by starting with a one-sentence summary and expanding it in stages into a paragraph, character summaries, a synopsis and a scene list.
Where the term comes from
Randy Ingermanson, a novelist who earlier worked as a software architect, describes the method on his own site. The name comes from the snowflake fractal. Wikipedia explains that the Koch snowflake is built in stages: the first is an equilateral triangle, and each later stage adds outward bends to every side of the one before. Ingermanson applies the same idea to a novel: begin with the big picture and keep adding detail.
His ten steps start with a one-sentence summary written in about an hour. Step two expands the sentence into a paragraph covering the setup, major disasters and ending, which he likes to structure as three disasters plus an ending. Later steps add character summaries, grow each sentence into a paragraph, then a page, then a four-page synopsis, and finally build a scene list in a spreadsheet. Step nine, writing narrative descriptions of the scenes, is marked optional, and he says he no longer does it. He also stresses that returning to revise earlier stages is expected, and that it is cheaper than finding a broken story after a long first draft.
An example
Dariusz Wren wants to write a cosy mystery set in a seaside bakery. In an hour he writes one sentence: a baker who cannot taste anything must find who is sabotaging her sourdough before the town's bread festival. He expands it to a paragraph with a setup, three escalating acts of sabotage and a reveal. When he writes a short summary for each of the three main characters, he finds that the rival miller has no reason to stay in town, which means the third act has no motive. Because he is still working with paragraphs, fixing it takes an afternoon, not a rewritten chapter.
Common mistakes
- Overbuilding the early stages and killing the interest in writing the story.
- Freezing the plan. The method expects revisions at every stage.
- Writing a one-sentence summary that is a theme or a mood and not a story.
- Skipping the character steps, which is where many motive gaps show up.
- Treating the method as a rule for every writer. It suits people who like to plan before drafting.
How to check your manuscript
Try stage one on a draft you already have. Summarise the book in a single sentence naming a character, a goal and an obstacle. If you cannot, the draft may need a clearer spine before more chapters. Then write the paragraph version and see whether the middle holds up. Related terms: story beat, subplot and stakes.
In Musael, the plan board keeps notes on every scene, so a scene list built from your summaries stays beside the draft.
