Only place I got any wrinkles was in the sideburn area and that `s only because I always apply tape to the skin, peel off the backing and press the lace onto it...if I don`t allow the lace to sit down `naturally` itself I can feel a little crease in it ..it`s easily rectified though... you shouldn`t get any undue wrinkles etc. if your template is accurate....but that goes for any system really.
