How to make paint paper glue with flour!!😳

Hello,I'm from Tunisia 😜 one day I went to a store to buy a glue to stick a paint paper on the wall of my room but none had a paint paper glue

so I decided to make one because I do have a really nice paint paper😍

And all you do need to make two liters of a paint paper glue

300 g of flour

2 liters of water

First you mix the flour with 1 liter of water very well and you put the mixture on a low fire but don't stop the mix and then add the rest of the water until you get a thick mixture

And then enjoy decorating your place with a homemade glue and a real nice paint paper😘
