This is the original recipe, it is ok, but it does not work too well. (Changes below)
1 tsp. cornstarch
1/2 tsp. water
1/2 tsp. cold cream (Ponds is the best, as it does not contain very much paraffin)
So, I started experimenting with it.
To make a good face paint, one that you can use water with, you have to have a base of WHITE, and use more cornstarch.
Go to Michael’s Arts & Crafts, or any craft store that carries white food color in a 2 oz. bottle, then add about 2 tsp. per recipe. Add more cornstarch, and this paint works great. You can use it just like watercolors.
