Hands down, before you attempt to tackle more stylish eyeliner techniques, you need to master the classic line. This is simply following your lash line from your inner to outer corners whether on the upper or lower lid. Classic lines pair well with liquid, pencil, and gel liners. But the real trick is mastering the art of lining your lids without pulling on them.
If you’re still mastering the classic line, using a pencil, liquid liner, or gel, start by making small dashes along your lid line as close to the base of your lashes as possible. Then go back and slowly fill in the spaces, being sure to maintain the same width as your initial dashes.
