4 - Further refines the look of the bangs and gives them a more natural look.
Using an inward clipping motion and working with a small amount of fiber at a time, cut the bangs to the desired shape. The character's style will determine how "choppy" they should look, but in almost all cases there should be some variation in the length of the ends.
5 - Prepares the rest of the wig for cutting and gives access to lowest rows of fiber.
Use the rows naturally present in the wig to divide the fiber. This will ensure a more even cut. Begin working on the bottom 3-5 rows, and keep in mind that the wig will appear shorter when worn. The bottom half of the wig especially will tend to stretch, particularly if worn over a large head (or someone with a lot of hair in a wig cap), so it is important to leave enough fiber here to properly cover things.
