It's like braiding in that it's not hard to do, it just takes practice to learn how to do it right and to get good at it. I posted a how-to link in my thread about the mane braid that I like.
You have 4 pieces, 2 pieces of mane, and 2 'pieces' of ribbon, even though it's really just 1 long ribbon, like somebody else said. You just cross the hair over the ribbon, then the ribbon over the hair. That's all there is to it.
I can't make a video, but I'm making a picture diagram to try to explain it. I'll post it in a moment.
