have a tip for you. I d been using eyepencil for years cause liqid eyeliner was too difficult to use. i couldnt make it look good. it needed some skills. but eyeliner much much better and looks sooo good. so i used a lot of ways to learn how to operate with it:) my tip:
take ur eyepencil and make it as sharp and thin as u can. make lines like u usually do but they ll be very thin. after this above the pencil line use ur liquid eyeliner. the pencil will not be seen but the gaps wich u ll make by ur eyeliner will not be seen eyether. pencil will also help you to form the right lines.
after u ll get skilled enough to use only ur eyeliner without any pencil help
