Okay, so building on my thought from some days ago: "Would a horizontally split, double braid base work for a braided Nautilus bun?"
Top braid is a five-strander (Just for fun) and bottom is a normal three.
This time, I have split the hair into two portions at the point where I find it the easiest: At top of ear level. I always end up having to spend quite a bit of time on getting the two portions equally thick when I have to do that.
If this turns out the be even semi-nice, this will be something I will be doing a lot in the future.
However, I do worry the smaller, bottom braid might "disappear" in the finished updo.
