Make a list of about 30 -ing words. Start with the first one that comes to mind, and then find the next word by either moving slightly sideway in the meaning of the word, moving to an opposite meaning, or picking up on the sound and finding another -ing word with similar consonant or vowel sounds. As the momentum picks up, discard the meaning-based sideways movements, and focus only on shared or adjacent sounds (i.e. trawling becomes growling becomes grinning).
Then write a story of no more than one page that uses every one of these words in any order. Let the -ing activity coax you into vividness, bigness, or brightness. Populate your scene with many characters doing all that action.
When you are done, read it back and make notes for yourself on what has shown up in the scene that’s curious to you. Consider this showing in terms of questions raised or themes broached. Consider this showing next in terms of images. Then moods. Then select a few characters who seem particularly full of life. You can save this set of things (questions, images, moods, characters) for something new, or you might ask yourself what they could lend to something you are already writing—an appearance, energy, or amplification that isn’t currently there.
