This braided criss cross headband style is one we've been doing for quite awhile with lots of different variations. The possibilities with this basic concept really are endless. This reminds me of a hairstyle you might see on a princess at a Renaissance Fair!
Start with a part from ear to ear and one down the middle. Inside out french braid one side from her ear up to the middle part. Only take hair from the front to keep the braid next to the part. When you get to the middle, continue with a regular braid at an angle towards the back of her head for a few plaits. Resume the french braid, taking hair from behind the temporary ponytail (again only adding hair to the front of the braid.) Repeat on the other side. It should end up looking like this...... Now, at this point you could either leave the braids hanging how they are. Or, pull them together in the middle as shown here. The gorgeous flower in this picture is from "Every Little Detail."
If you wanted to keep going...... Take a little hair from underneath the french braid on each side and make some tiny braids. This is where you could do pretty much anything you wanted! Make some kind of a design with the little braids by stringing them through the french braids. I just used my finger to poke a hole through the french braid as a guide, then followed the tiny braids right through. Create the design you want, then tie everything together at the base with an elastic.Add a cute hair accessory and some curls. (This darling flower also came from "Every little Detail!") She told me she felt like a princess. :)
