This is Halloween 2009. Belle is obviously dressed as Cinderella. Sweetheart (not so obvious) is Calvin and Hobbes. It has been some time since I did her hair, so I don't know exactly how I did it that day, but I've tried to recreate it here for you. In the picture above, I actually had bought a headband and covered and stitched it with fabric to make it blue (since I couldn't find a blue one in the store). She lost it at school, so this tutorial is showing another headband that has a huge bow on. it That's not quite appropriate for Cinderella, but it's the best we've got now. And yes, I know it isn't Halloween yet, but perhaps your little princess likes to play dress-up...
To begin, put the front half of the hair in a pigtail with the elastic at the part (elastic is not temporary) and twist it up and clip it out of the way temporarily. Gather the back half of hair as if to put it into a low ponytail.
Begin twisting the hair.
Keep twisting. You may need to make some minor adjustments to the hair that is going to start pulling over the top of the twist by shaking the tail gently or using a comb to guide it across smoothly.
Undo the clip in the front. You now have two tails sticking out at nearly the same place. Next you will roll and wrap one of the tails around the other (it shouldn't matter which) to make a bun with a tail sticking out the middle. Pin it in place.
Keep rolling into the loop until all the ends are in a circle.
