Luckily, Zephie's hair is not very complicated, so the flipped out curls did not have to perfectly even or even the same size.
I started with a long, dark brown wig.
I used a regular scissor to cut the layers, cutting at an angle to keep the hair looking natural. (Zephie's hair has 2 main layers--a short one, then a few long strands at the back)
A liberal amount of hairspray was used at the bangs to separate the sections.
For the short layer, I used a large barrel curling iron, which I had to turn on, then turn off once it was heated as the lowest heat setting was still too hot for the synthetic fibers. I wet the piece of hair I was curling, and clamping it in the iron, rolled it towards the scalp. I held it in place for about 20 seconds. If the hair sticks to the iron, you know the fibers have melted :\
I wrapped the curl around a toilet paper roll (I didn't have large rollers) and bobby-pinned it in place. I kept each curl around the roll for about 1 minute.
Keep in mind this is NOT the best way to curl hair, but I just used what I had, and watched a few video tutorials online. When I figure out a more efficient way I will explain in further detail or post a video.
