For this, I got three long pieces of cloth, stretched them a little to fray them, sewed them together, braided them, sewed them together on the other end, and attached a piece of elastic to stretch around my head.
Apologies for the terrible photo. i could not find a mirror that had enough light. the right side of the waterfall twist fell apart when i was making the long twist bit. maybe if i had done it all anticlockwise. this hairsyle is much easier than it looks! i saw the waterfall twist section online but i made up the long twist bit myself, although i am sure it has been done. it is the same technique as the one i use for making cordage out of natural fibers, like raffia and brambles.
