Benefit #7: It teaches your hands positions that are useful in advanced needle techniques.
When you begin to practice the one-handed turn, you will find it awkward to glide the handle of the needle over your fingers. As you practice, and the movements become smoother, you will train your hands to better move in ways you will need to when manipulating the needle during insertion. There are many of the more advanced techniques that become easy to learn if you have practiced your one-handed turn. Even rotation and pecking, however, become smoother, easier, faster, and require less effort after spending time practicing the turn.
