Stolloween has a great guide for beginners such as myself and his work is truly inspirational. I deviated from his recipes quite a bit because this was such a small project. For my papier mache I used a mixture of equal parts glue and water and here are the details on my paper clay.
Next I worked on the skull and eyes. I wanted the thickness of the skull to thin as it got close to the edges of the binder. I cut angled rings from a toilet paper roll to frame out the nose and eye sockets and then built up layers of paper clay. I wanted the eyes to be smoother so I used air dry clay.
This mixture of paper clay was made with mostly white paper with a few pink, orange and purple sheets. This color combo along with the texture happened to create an interesting fleshy looking bit in the corners of the eye, so I left some of it exposed.
After it was all done, I dripped some more acyclic clear coat onto the eyeball swirling it around by rotating the book instead of brushing it on. Letting it collect in the corners gave it a very wet look.
For the fingers I rolled newspaper around straws, taped the end of the paper and then cut them into finger joint length sections. I glued these into the position I wanted them. Then started building them up with layers of paper clay, especially the knuckles and putting indents where the fingernails would go.
The hand along the spine was cut in half so the binder could open and close. I had recently seen this and while my little project is no where near that caliber of artistry the idea of stitching flesh called to me.
I cut the skull teeth from plastic which wasn't the best idea. I ended up adding folded paper to each tooth to make them a thicker. A thick cardboard would probably been better to start with.
