I did a fishtail braid on Vida once. I used to do my own with one but I've gotten lazy and just put it up in a ball on top of my head
A fishtail is a pretty easy braid to do too, it looks more complicated than it is. Just a 2 stranded braid that you add a little hair into the opposite side as you go down. I need to take some pics when in the tail braiding mood.
