When developing measurements for a hairpiece, creating a pattern is the most suitable approach as it provides a physical representation of the patron's head size and shape. This allows for the hairpiece to be custom-fit and accurately placed on the patron's head. A blueprint and artist's sketch are not ideal options as they are typically used for construction and design purposes, not for measuring the human body. While a photograph may provide a visual representation of the patron's head, it may not accurately capture the measurements needed for a hairpiece and is therefore not a reliable method for developing measurements.
