Give the sample a repeatable point of reference
An exploratory sample is easier to discuss when it includes a simple visible reference mark, such as a date, file label, or test area. The mark lets a maker connect a photo to the exact planning notes used in that session.
Record what was observed, not what is guaranteed
Describe the visible sample condition and the next question to test. A single sample does not establish a general material guarantee. Browse /updates/ for more sample-documentation ideas.
