I would kill for hair this long and thick -- Beautiful simple braid. To make: french braid a section of your hair on either side. Once they reach the back, braid the rest down. This works better with thick hair.
Spoon: Another hack is to use a spoon. The handle of the spoon should be placed at the corner and the eyeliner should trace the handle. Now the curved portion should cup the eyelid and helps to create the curvy tip of the eyeliner.
