Prioritize identification at real viewing distance
Small type, narrow outlines, and low-contrast color combinations can disappear once the patch is molded and viewed on gear. Share the distance and lighting conditions that matter so the proof can prioritize the necessary symbol, name, or identifier.
When the patch is decorative rather than functional, say so. The design can then allocate more space to relief and character detail instead of treating every element as critical information.
