Firstly, let me say that this is as easy as it is possible. Look at
my army to see many examples.
It basically works like this. Start by mixing a small amount of
GS. Then, put down a VERY thin coat of superglue on top of the head. Smush the
GS down onto it, wait a few minutes for the superglue to dry (superglue and
GS behave strangely with each other).
Then, you start crafting the hair. This involves making a lot of parallel and V shaped strokes in the
GS until you get what you want.
