Pin the twist at the nape of the neck to hold it in place. Grab a small piece of loose hair from the left side of your head and bring it over into the right twist, rolling it in. This is going to help you change the direction that your twist is going (from right to left). The piece should be diagonally parted, so that when you twist it in, your hair will begin to go in the opposite direction. The goal is to create an S-shape with your hair.
