First tie your hair in a pony tail. If you want the style in your pic, tie it low. I tie mine high "cause my hair gets hot.
Twist like crazy until the end.
Wrap that around the base of your pony tail. Hold on to the end.
This is what humblestumble meant by up then down. Insert the stick into a small part of your hair from the bottom. My stick is upside down. Sorry. The end I was holding is still between my thumb and forefinger.
Insert the stick with the hair on it into the top of your bun. Wiggle it into your bun and out the bottom, making sure that it comes out through your bun, not behind it.
Example of how to hold the end while wiggling the stick.
Inser the other stick through the bun not behind it. This step isn't as crucial to me to insert it the same way as the other stick, but you may want to.
