On your netbook you will open a new Google Drawing document and add your 6 portrait photo's of yourself to it. You will then follow the instructions on THIS SLIDE to add 4 different colours to the background, your hair, face and shoulders. You want your background to be one solid colour.
The best way to do facial features is to do them first using the curved line option. That way you can make soft edges around your mouth, eyes, nose etc. Make these lines transparent so you can see if you've traced over it as accurately as possible. Once you're happy with your facial features colour it all one colour!
Repeat this process on all six of your portraits.
