2. Open the image jerilarge.jpg, jeri-posterized or an image of your choice in Adobe Illustrator. I am working with jeri-posterized because not even I am sure whether this will turn out good - but good artists can always through their art away and work on another.
3. If the image is too small for you to work with (I recommend that you enlarge it), make it larger. First, Windows users: hold down CTRL + 1. The image will go to 100%.
Enlarging, if the image isn't big enough, can be done by clicking, then right clicking on the image itself and going to transform, scale..
use this setting...
Uniform *
150% for mine... you can use less or more if you are at a higher resolution.
Press ok.

Then Save...

4. I saved my image as jeri-posterized.ai Your illustrator might ask whether to save the vector in a current version or less. I am using 8.0 - even if i use 10 usually. Use the most current version that you are using.

5. Good stuff.. IMPORTANT THAT YOU FOLLOW ALL THOSE TINY DETAILS

- make sure your tool menu is opened. If not, go to Window - Show Tools on the menu bar

- go to the layer tab if it's not opened press F7 or go to Window-Show Layers

Be familiar with "hide layer" and "new layer" also, "drag layer"
hide layer: This eye hides the layer from other layers.
new layer: that creates a new layer.
drag layer: depends on your ability to click on your mouse and drag a layer to another :-)

- go to Windows -- Brush libraries - Calligraphic : Choose a substantial brush This is mine:

6. Create a new layer. You can change the name by double clicking on where it says "Layer 2" in "Name" I called it base skin.

7. Make sure base skin is the active layer and select the eyedropper tool on the tools menu:
8. Select the closest lighest portion on the face...

9. Make sure that "Base Skin" Layer is active - it should be highlighted. Select the paint brush tool from the tools menu it's an important tool in all my vectoring. It's important that the fill color in the tools menu look like this:

it's important that the background has a slash through it - AT ALL TIMES and that your colors appear with the foreground fill color infront of the other.
10. Now, take your time and trace a base... you dont need to make this perfect since you can always put layers on top to fix it.. This is how I did mine:

11. Create a new layer, call it "darkest" then hide the layer called "Base Skin". Make sure that the "darkest" layer is highlighted and once again select the darkest part of the face. Then trace around the dark areas of the face with the pen tool again. Try to make it as porpotioned as you can without following the actual posterization of the face but close enough- mine looks like this when I reselect the hidden layer.:
