Final answer:
A drawing mat is a flat leather pad with fine teeth used to grip and separate human hair extensions for braiding without disturbing the surrounding hair.
Step-by-step explanation:
A flat leather pad with fine teeth used to sandwich human hair extensions so a specific amount of hair can be extracted for the process of braiding is known as a drawing mat. When adding hair extensions, a drawing mat ensures that hairstylists can work with small, precise sections of hair, maintaining an even distribution without untangling or disturbing the remaining sections. The fine teeth of the drawing mat grip onto the extensions and natural hair, allowing for an effective and smooth braiding process.
