lots of good paper mache info here: "A few months ago I developed a new recipe for a sculptural material I call “paper mache clay.” This material is so easy to use and so easy to make that I now use it exclusively for all my paper mache sculptures.
The Roost Papier-Mache Piggy Bank is a delightful papier mache pig and is quite fun to use. Put coins in the pig until chock-full. When you pull the hind leg string the pig's hindquarter is split and it spills its loot.
This homemade clay recipe only takes two ingredients and 10 minutes! 2 Cups of Baking Soda, 1 Cup of Corn Starch, 1 Cups of Cold Water. it is so much cheaper than the store bought model magic! Air dries and can be painted.
