Format the finished story for a shareable anthology, with a title, byline, and consistent formatting suited to a compiled collection.
An anthology is a collection of pieces gathered together, often from multiple writers, meant to be read as a set -- which means each piece needs consistent formatting (title, byline, matching font or handwriting style, page numbers if printed) so it fits alongside others without looking out of place.
The title and byline do real work together: a strong title hints at the story's tension or theme without giving away the ending, and a byline, "by [Name]," signals ownership and craft, the same way a published author's name appears on a real book or story collection.
Mastery looks like: They format a finished story with a non-spoiling, tension-hinting title, a byline, and consistent presentation suited to a shared anthology.
Common stumbles: Choosing a title that reveals the climax before the story is read; leaving formatting inconsistent with how the rest of the anthology is presented.
