The dutch braid. The "under" braid. The reverse french braid. There are a bunch of names for this braiding technique.
Basically, it's a french braid created on top of the hair, instead of underneath. And it's not much more complicated than a french braid.
When I was learning to braid, I taught myself this way first, and then had to take more time to learn the classic french braid.
Here is the tutorial for you!
(don't count the ## of times I say the word "under". It's just too many.)
