Hey guys, its me again, bringing you another awesome tutorial, a lot of people are wanting to draw eyebrows, and im going to show you how today.

First things first, youre going to need the yf body template, which can be downloaded here if you dont already have it.

Were going to use this texture as a reference, so we know we're drawing the eyebrows in the right place.

1.) Open the image in your 2d editor, and make it void of color. (in photoshop go to Image-Adjustments-Desaturate.

2.) [OPTIONAL] When i draw something like this, that i know im going to want it to have a lot of detail, so i like to double the image size, so instead of 2048x1024, i make it 4096x2048.

Lets draw a solid alpha for the eyebrows using the pen tool. (or you can do it by hand depending on how good you are with control of the mouse, and if you have a drawing pad for this even better!)

1.) Make sure you are on the alpha channel, as this is the one we will be drawing on.

2.) Select the pen tool; its toward the bottom of the list of cool gadgets to the left of the screen. (Hotkey: P)

3.) make a line going from one end of the eyebrow to the other, by clicking once at the inside of the eyebrow, and then again at the end, the pen should automatically create a path.

5.) You can drag the anchor point around by holding Ctrl while clicking on it. We can also do this with the other points to move them around.

6.) After I'm done editing my path I get a line looking like this. This is the way I want my eyebrows to curve.

change the brush settings (the icon on the top right that looks like a little cup with brushes sticking out of it) under the tab shape dynamics activate fade, its located under the drop menu labeled control , the one at the top, not the bottom. and make it whatever length you want, fiddle with it a bit until you have the right size for your eyebrow.
