I will hold the skin at the corner of your eye bone area (or if you have eye shadow on, then use a Q-tip), that will help to line your upper eyelid. "然後由中間開始,貼著睫毛畫到眼尾 由內眼角畫到中間, 最後眼尾再輕微拉長,拉尖" is good, so that you will not put too much eyeliner @ 內眼角.
Try to draw the liner as close to your eye lashes as possible. If you are not using Mascara, you could draw another line underneath the lashes.- pull the skin near the eye bone above your eyelid, look up a little bit and then draw the line underneath and between your eyelashes...
I'm now using Dior's liquid eyeliner, pretty good cuz the tip is 夠尖, very soft, easy to handle, and do not smudge.
Or I like to use Shiseido's gel eyeliner. They come with a small eyeliner brush.
I am using a flat, small angle brush for eyeliner. I found it easier to form a straight line and a nicer 尖眼尾.
If you want your eyes look bigger, draw the middle of your eyeliner thicker and keep the 眼尾part short.
If you wanna have longer looking eyes, draw the 內眼角 thinner, and draw from 中間 to 眼尾
thicker, and then finally 拉尖.
After all, you just need to practice over and over again, then you'll be a pro!!!
