When I go walking, my mind is cooking on my YA novel. When I get back home, I try to get it all "on paper". Here's a brainstormer exercise:
1.) Set one character in a surrounding (home, cafe, street).
2.) Imagine what is in that space and list it. If it's a cafe, list the coffee maker, the customers, the wet towels. Find photos on Google.
3.) Make a Photoshop collage
Congrats! you now have a visual model to write yr next session.
