I have just made another batch of cornflour dough for mardi crafts. Here is the recipe if anyone fancies trying it.
1 cup of cornflour
2 cups of bicarbonate of soda
1 1/4 cups of water
Mix in a heavy-based saucepan over a medium heat and keep stirring until it thickens like mashed potato. Immediately take off the heat and plop out onto a board. Cover with a damp cloth until cool. Then roll out and cut out shapes. This will air dry in a few days. If you make a hole with something like a chopstick in the top you can hang them up for Easter.
This mixture makes a really smooth dough and will take gentle sanding and painting
