I'll be using M.A.C.'s black track fluid line and a small eyeliner brush this one is by sigma
When doing a small thin line, I start at the middle of the lid and pull it back towards the corner of the eye.
Now you have to bring it in to the inner corner of the eye I like to do it in small strokes pulling it towards the middle. Make it thinner at the inner corner and slightly thicker as you go out.
And we're done :)
When doing winged liner, I like to draw a line from the edge of the lash line and bring it out like it's all one line.
Then I connect the end of the line to about the middle of the lid and smooth it out.
Now we have an empty triangle
Now fill it in!
