This is my process for doing small twists. Of these I had 600ish. I started with the front of my head and then moved from the nape of my neck up. They took 15 hours over 5 days. I started them June 1st and they lasted until July 14th. So about 6 weeks of wear. I was able to swim with them (in the ocean 3 times and in the pool twice) and wash them each time after that. That made it a lot more difficult to take them out though.
Super small twists are my favorite summer style.
