The next step is the planning stage! You will cut your embroidery string based on how much of each quality you’d like to carry with you. This will be different for every person, and every instance of the spell. If you are planning a busy work week then maybe you need extra luck? If you’re a student and have an exam then maybe intellect would be better! It is your hair and your spell so gauge based on your life.
The final and longest step is going to be actually wrapping it up! I suggest putting on a good movie and planning to take breaks depending on your hair length. In my case I have about waist length, so this takes a moment. To start tie a knot at the base of the braid wrap the string around it. You will need to continue the wrap until it is the thickness you prefer. I have done it very thin and thicker to make it more visible.
