Just a little idea I had about the hairdos of Avatar. A couple days later than promised, but I forgive me because of special circumstances. Like papers and birthdays.
EDIT: Aw, c'mon guys, hair ain't *that* hard to braid! Toph had her hair fancy and braided for the Earth King's awesome birthday bash! ^^
In my fan fiction, I actually had Katara teach Aang how to braid Toph's hair so he could teach Toph how to braid Katara's hair. [link] I did wonder about Toph's fancy hairstyle in Ba Sing Se, I guessed that Katara was probably the one who did it.
