Quick walkthrough of female head creation.

First of all cover ALL tabs with double sided sticky tape, then cut out.
This is probably the piece that seems confusing. Its actually the back of the head and the base and front of the neck. When you crease it so it looks more like.....

this, you might have a better idea of how it should go.

The front part being the front of the neck.

What you want to do is stick this to the sides of the front part of the head. Ignore the parts around the jaw for the moment.

The back makes up a solid shape like this...


You can then go onto stick the jaw together once this is done.


The hair folds and sticks around the top of the head like this, so the top sections build up to make the top of the head / hair instead.


Hope some of this helps
