start at the front, divide hair into two and twist. incorporate hair with each twist. do on both sides until you get to the back of the head. tuck ends in on opposite side of the twist in the back of the head and bobby pin to hold.
I love this bun and it's VERY in right now! I don't use a sock though. I put my hair in a loose high ponytail and twist the hair loosely around. I pull the bun to loosen it a bit and voila! Perfect idea for Dorie's hairstyle!
