Here’s another good paint recipe (one of my personal favorites) which keeps for a week or two…
1) In a saucepan, slowly add 1 cup of water to 1/4 cup flour and stir till you get a smooth paste,
2) Heat saucepan and stir paste till it thickens,
3) Let it cool completely,
4) Divide paste evenly into 4 portions,
5) Dissolve 3 tablespoons ground blackboard chalks (choose any one colour) with 2 tablespoons of water and 1/2 tablespoon of liquid detergent and stir into each portion of paste,
6) Store covered.
