Paper Mache Projects

I belong to a Halloween Group and in this group is 1 of the greatest papier-mâché artist I've ever seen, he gives you detailed Instructions and recipes, I have made a pumpkin head for my scarecrow, large rocks to hide my lights and I am working on a huge spider.
What I like about his recipe is when they're dry their extremely hard, I tried some in the past and they never become very stiff. Heres a link to his Web site http://www.stolloween.com/
