Okay, recently I decided to cut the bangs on my wig without really thinking about it, and cut them too short (there's a noticeable gap of skin between my eyebrows and bangs). It turned-out to be one of those things that I instantly regretted doing, and I'll be sure to take my time and make sure I know what I'm doing with any future wigs.
However, is there any way to save the currently existing wig, or should I just move on?
EDIT: Thanks so much for all the wonderful advice! I never really expected such a response! O.O It turns out that pulling the wig forward on my forehead was all the simple genius I needed, and I had a trusted friend even-out the bangs (should have had her trim them in the first place...).
