Let us begin with our bare eyebrow, yes mine looks horrible =p
First, you take a very sharp eyeliner or brow pencil closest to the color of your eyebrows. A lot of people are against using black for fear of it being too dark, but if you have a light hand you can use it. So I am using black. Then lining right above my natural line. (If you do it under your natural line, then your eyebrows may look too thick)
I made a rounded shape on my arch since my eyebrows tend to make a pointy shape. But if your prefer the point then you can create that too
Moving on.. take a small brush with an eyeshadow closest to your eyebrow color. Again, I am using a black eyeshadow. Shade in your brow using light strokes until the desired fullness is achieved. Top it off with an eyebrow gel to set it all in and you are done!
Here is my finished eyebrow compared to my other unfinished brow. HUGE difference right?? Well I hope I helped, keep practicing and soon you will be able to transform your brows into whatever you like =)
