It’s really easy to make your own Papier Mache Paste using just household flour and water.
I don’t really follow a recipe but a general rule I follow is 1 part flour to 4-5 parts water. Depending on the quantity of paste you need to make you can use anything from a coffee scoop to a cup. You’ll also need a saucepan to gently heat the paste.
The method is really similar to making a white sauce for cooking.
Add a scoop of flour to a saucepan and add an equal measure of water. Mix together making sure you smooth out any lumps. Gently heat the mixture on a low heat until it thickens and turns a translucent colour. Now keep adding a little more water at a time making sure that you get all the lumps out until you get a white sauce/custard consistency. Remove form the heat and pour you finished papier mache paste into a bowl to cool.
To store it cover with cling film and keep in the fridge.
