Start with a ponytail. We are going to make a fishtail braid going down the body of the ponytail.
Start a small braid just off center. Hold the strand that is on the right, let the middle one hang, and then reach under the pony tail and grab a strand of hair from the right side and bring it under and around the pony tail. This strand becomes your left braid strand.
*The braid done in this Instructable is underhand (like a cornrow is done) rather than overhand. You can do this braid with either method.
