Write to describe
Step 1 · Pick a prompt
Pick one prompt. Choose a place you can walk through with your eyes closed, because your reader will be doing exactly that.
Step 2 · Plan it
Plan first. Fill in the five parts of the Path in short notes. A good path on paper is a scene the reader can walk.
Step 3 · Pick one goal
One goal, chosen before you write, beats ten wishes after. Pick exactly one.
After you write, look for the proof in your own sentences.
Step 4 · Write your description
Keep to your one path, let the things themselves do the acting, and give the reader more than their eyes.
Step 5 · Sum it up
One more thing, once you have written. One sentence: what should the reader see, hear, and feel when they stand in your scene? If your description and your sentence disagree, believe the sentence.
Step 6 · Before you turn it in
Read your description once, out loud if you can. Then check.
