Start with your braids or twists that meet up in the back. You know the problem with this... by mid day you have a mess of that hair that is not secured anywhere on top. Well--- scroll down to see our solution.
Combine it with the braid that is now below that second knot because you dropped it between the knots. And secure a CLEAR rubber band to all of the hair. The knots and the braids. And pull it tight so it hides itself underneath the pony tail.
