How Do I Tie A Chonmage?

[Skit]

Hiya,

I've been wondering for for a while, how do I tie a chonmage?

I've tried running searches for it using google, but no look. Most I've found is what I already sort of knew, ie. it's used by Sumo, and was popular with Samrai 'til being banned during the Meiji period. But nothing on how to tie one, aside from mentions that they use oil and lots of combs...

Any pointers?
