Not going to go into detail until it's complete but here's a few tidbits about the project.
1. Papier Mache is being used. Yup, big surprise.
2. Very large, too big for doorways so it's being constructed in sections that can be assembled for display.
3. The project will be using several new techniques that have resulted from experimentation.
That it, all you need to know.
