You will need to take small section so we have a lot of bubbles. use elastic that match your hair color they don't completely hid when finished.
Start with a pony tail at the base of the neck
Make a second pony tail just above the first one
pull hair up for a third pony tail but don't elastic it off yet. Take the first pony tail you did and split it in half. You will take the halves on each side of the second pony tail and place in the third pony tail.
you will continue this pattern all the way up the head until you get to the forehead. You will need to be really close to the forehead. you will always have 2 pony tails.
Once you get to the forehead pull the hair out a little in each of the bubble to make the bubble look bigger. Now you will now be working with 2 pony tails. take the back one and split it in half take each half and wrap it around the front pony tail and elastic it off under neath the top pony tail. keep repeating till you get to the end of hair. then go back and pull each bubble out a little to make that bubble bigger here as well.
Now you will take the end and twist it back down the right side of the knit braid and bobby pin off. do not fold the hair over it will show that back of the elastics and not the braid you just made. tuck the end of the hair that you could not fit into a bubble up so it is hid under the braid. You will then need to add a lot of hair spray or gel to make sure there are no fly aways. Bobby pin down any fly aways that are in the braid its self.
It may seem confusing but try it a few times and it will become easier the more you do it. watch the videos they will be helpful to see how they do it.
