How to with Brushes! DEB: Def. Help. I have a question...I understand that real hair brushes are the best....and very expensive. I mean $10 for a fake foundation brush is a lot,to me. AND HURTS! Do you think it gross to make your own customized with YOUR hair? Yay or Nay? I am personally considering it because the fake brushes do hurt.The only one in my set now, that I adore is the eyeliner brush.
