I promised I would post some variations on my chains, so here you are:
Start by making a part from ear to ear. Put this in a temporary elastic. Pull the rest of the hair back into a ponytail. Take the hair out of the temp and divide into as many sections as you want, (I did 7.) Make a chain in each section, and add to the ponytail. For full chain instructions, visit my label for chains. Now, you can make a messy bun, that's it.
This one is actually much cuter in person. It's hard to see the full detail from the pics. Try it on your own princess and you'll see what I mean.
