Try to leave the front edge alone because the hair is added differently along the edge to make the hairline more natural.

To reduce the size of a 10" long X 8" wide stock piece to your exact size:

1. Make a template according to the guidelines elsewhere in this FAQ section
2. Tape the stock unit to the top side of your template, aligning the front edge.
   
3. Cut the shape out with a razor or scalpel from the bottom side. (Using scissors may cut the important edge hair short - not good!)
