Here are some thoughts about creating flash fiction.
A writer should keep in mind that words are symbols and these symbols create a narrative in the imagination of the reader. I like to say that the reader is at least 50% of the creative process.
The writing of a flash fiction short story is always a series of choices and decisions on the part of the writer; with the writer working within a very finite word limitation. This word limitation should never be looked upon as restrictive. To the contrary, the word limitation is an opportunity to place the right words in the right order, so that the words left out of the story are implied by the words left in the story.
And here’s another thought. Of necessity, the narrative movement in a flash fiction story is usually small or even slight. Too much narrative movement will capsize the story.
Flash fiction is best when it captures a very finite period of time, when it possesses unity of place and time.
Once again, none of these thoughts are original with me. These are just thoughts I’ve pondered as a student and practitioner of the flash fiction short story.
