The way you part your hair for this braid will effect the outcome. I recommend starting at the top of your head but towards the side (of your choice) to create a pretty side part.
Begin french fishtailing on the top side of your head (to french fishtail, start with two sections and cross over each other, than continue to fishtail while gathering pieces as you go).
While doing your braid, guide it diagonally across the back of your head. Once all hair is gathered, secure with an Elastic.
Tightly fishtail the hair secured within the elastic and secure once again with another elastic. Then wrap the end of the braid up into a twisted bun. This should give a ‘seashell’ look. Secure with bobby pins once finished.
