First start off by gathering a small amount of hair and put it into three sections.
Start by crossing the left section over the middle section.
Next on the far right section gather more hair and attach it to the strand, then cross it over the middle section.
Then repeat this process all around the head until you get to no hair left and all the hair is in the french braid.
With the hair coming out of the braid, do a regular braid (as in step one) down and tie it in a hair tie.
