I just know there are a lot of you out there looking for helpful liquid eyeliner application tips. How do I know? Because I need them too! I love liquid eyeliner, but I've never been able to put it on properly, without fear of looking like I'm trying to recapture the two weeks in high school I spent as part of the Goth subculture (no, it was not pretty; I much preferred my grunge phase). Fortunately, you don't have to make yourself look like you're crying black tears of pain and sorrow. You can not only wear liquid eyeliner, you can rock it out. Just follow the awesome liquid eyeliner application tips I found!
Since my whole problem is being able to draw a straight line, this is the most essential liquid eyeliner application tip I can give you: start with a pencil. Liquid liner is meant to go right above your lashes, so making a straight line can be hard. Make a dotted line with your pencil instead, and then follow along with the brush on your liquid liner. It will be far, far easier. It's also better if you start in the middle of your lash line, and go out in either direction.
