Here is a very easy recipe for clay that is safe for kids
2 cups baking soda
1 cup Argo Corn Starch
1 1/4 cups water
Mix cornstarch and baking soda, add water and mix.
Bring to a boil, stirring constantly, until is thick like mashed potatoes.
There you have it clay ready to form into desired shapes.
Let it dry for 36 hours.
Paint and you can also coat it with shellac or clear nail polish.
Please use your judgment of what parts kids can make depending on the age of the children :)
Please let me know what are you working on in the coming weeks :)
