Ensure that the fibres of the brush are evenly coated the whole way around with your product of choice. Rest the brush on your middle finger while holding it in place with your index finger and thumb. This will help to control the movement of the brush and achieve more accurate line work. Hold the point at a slight angle to the skin and allow the long side of the fibres to help create the line. The tip can then be used directly to sharpen or add a tapered point to the eyeliner.
