This document provides detailed historical instructions for making a fly fishing line by hand using horsehair. It describes procuring the best quality horsehair and dividing it into three equal portions. The hair is then twisted together using three small wooden sticks in a specific winding process to create a strong, knotless line. As the line is twisted, individual hairs are periodically cut and replaced to ensure the line retains full strength and tension throughout its entire length. Mastering this traditional line making technique requires careful attention and multiple readings to understand each step. The included woodcut diagram aids in visualizing the twisting process. Overall, the passage conveys the skill and time involved in crafting high-quality fly fishing gear before the availability of modern manufacturing methods
