01
Keep the observation beside the source
Start a sheet with four fields: source, date saved, observed feature and open question. In this example, the observed feature is the alternating strip pattern, not a conclusion about why viewers like it. The question might be whether wider spacing changes the rhythm of a flat composition. Keep the photograph or a reference to it beside the note, and record any attribution needed before sharing. This small amount of context makes the fragment easier to return to when the initial impression has faded.
02
Change one feature in a bounded study
Make two paper arrangements using the same number of strips and the same light and dark sequence. Keep one arrangement closely spaced and give the other wider gaps. Label them A and B, then write “spacing” as the feature intentionally changed. This is a composition exercise, not a controlled scientific test. The limit simply makes the comparison easier to discuss. Avoid adding new colours, textures and shapes at the same time if the question concerns spacing; those can become separate studies with their own notes later.
03
Record a decision without inflating the result
Complete the sheet with what you noticed, what you prefer for this study and what you might try next. A fictional entry could say that B leaves more blank space between strips and will be kept for a future page-layout sketch. That is a choice about the current composition, not proof that B is universally better. Save both versions with their labels so the comparison remains available. The resulting record links the original fragment, the chosen variable, the two arrangements and a possible next step without requiring a finished project.
