I've had 11 people email me and 2-3 people leave comments that they've tried this heart hairstyle and just can't get it. I must have done a really bad job at explaining it the first time! Hopefully this video will help. I put in the small pony on top and regular ponytail with the braids before I started. I figured you could probably do those on your own. :)
We did have at least 2 successful attempts already though. Look how cute these turned out! Heather sent these in to show that it can be done, even with shorter hair! Here it is on her older daughter. (This adorable bow is one that she got from Bows 4 My 4 Girls!)

Here it is on her younger daughter with even shorter hair. Notice how she started the ponytail up a little higher on her head to give her more length for the braids.

See people, it can be done! Give it another try!!

Start by making a half pony. (I went further down on her head than I normally would.) Split the half pony into 2 sections and braid each section. I did
When you get back to the bottom with the other braid, tie the end into the elastic. You can finish this however you want. We did a messy bun. 
I actually crimped the top of her hair before starting this, just to give it a little more texture.
