Awesomeguy's Wig Cutting Tutorial Part 1

I was just wondering... I'm designing a full costume part of which requires parts of a wig to be cut different ways. The costume I'm designing is a jedi costume with a 'somewhat' narrow strip of hair left long, right along the middle of the head, while the rest is cut probably into a pixie cut (I haven't gotten a chance to design the hair yet), save for a small amount behind the right ear. How would I cut the short pieces, so I achieve both a natural look, and the style that I want?
