Facts first, then the scene
You don't need to see a place to write it. Build it from what is true about it.
Steps to follow:
- Pick a place your character is standing in. Don't try to see it.
- List eight facts about it: three sounds, two physical sensations, two things someone might say, and one thing that doesn't belong.
- Circle the three that interest you most.
- Write one paragraph that moves through those three in order, one sentence each, with a connecting sentence between them.
- Read it aloud. Cut any line that only says what something looks like unless the story needs it.
