Tips for Writing Flash Fiction
Start in the middle
You don't have room for setup. Drop the reader into the moment that matters — the argument already in progress, the discovery already made, the decision already weighing on the character. Let the reader infer what came before.
One scene, one moment
The best flash fiction captures a single moment with the intensity of a photograph. Don't try to tell a character's whole story — find the one moment that reveals it. A story about a marriage doesn't need the wedding and the divorce. It needs the moment she stops reaching for his hand.
End with a twist, a revelation, or an image
Flash fiction endings need to land hard. The final sentence should reframe everything that came before, reveal something the reader didn't expect, or leave an image that haunts them. The ending is doing most of the story's work in flash — write it first if you need to.
Cut ruthlessly
Write the first draft without worrying about length. Then cut. Remove every adjective that isn't earning its keep. Delete every line of exposition. Trust the reader to fill in the gaps. Flash fiction is the art of what you leave out.
