iamme.... I have never cut a base so please use your own judgement..... leondon90 will be able to answer you better than me,
but I`d imagine you would/could sit the system onto the template and hold them together by pushing a few short pins through,
and then trim/cut the outline.....I wouldn`t wet the hair either. Hopefully he`ll get back to you today as you`re probably wanting
to get this done ...Paul.
