Pull the topsy tailer up to make an inverted turn. Gather another piggy a little ways down from the first and secure it.
Divide the hair from the top piggy into two equal sections. Braid them and secure them with a temporary band or clip. The braid shouldn't be too tight or it will be hard for it to curve around. Also when you begin braiding, start with the side section that is near the center of the head rather than the one nearer to the ears. This will help with the curve and will prevent the braid from rolling out of shape.
Curve the ends of the braids around in the heart shape and stick them together with the other piggy. Put another hairband around all of it. Undo the temporary bands or clips.
