I have never cut a lace base on a stock system before and am wondering if you can tell me how to cut the base without cutting the hair that would lay over edge of the cut? I am assuming this is best done with the system upside down on a styro head with the template pinned over it? Using hair clips helps a little but it seems hair is always in the way. Also, using clips presents challenges when turning the hair system upside down on the styro head to make the cut as the lace no longer conforms to the styro head with clips underneath. Any help you can give would be much appreciated.
