I got this recipe from someone who works at the National Library of Wales in the book binding department. I was told it is traditionally used to stick the leather to the hard cover of the book (usually called the case). It also is a great substitute for PVA when sticking paper together, or making paper-mache.

The Recipe

Add 60g of flour (not self-raising) to 500ml of water in a saucepan. Pour it in slowly while stirring to avoid lumps. Bring the mixture to the boil then turn the heat down to let it simmer for 5 minutes.

Afterwards let your new glue sit until cold. It will only keep for a few days so use it quickly. To stop it drying out put the glue in a container add a little water, it should just sit on the top, don’t mix it in. Seal the top and leave it.
