I've been seeing this one everywhere lately. You don't have to have super long hair, either. Tie it off where ever your hair ends, or use an X shape with two bobby pins right by the scalp without leaving at tail braid.
Part out the section of the front you want to braid. I used a bobby pin to hold the back hair out of the way while I braided.
This hairband from Gimme Clips is a flower stuck onto the band. I like the decoration. To add a hairband with a bauble on it, position the pretty in place first, then wrap the rest of the band around beneath, being careful not to catch flower petals or whatever in the loops.
