I have seen pins on Pinterest for a while now about making your own version of glues, including types of homemade Mod Podge.... so thought it was about time to give it a go! The 'recipe' I tried was based on this post by Ways & How
Stir regularly and simmer for about 10-15mins (but make sure you don't let it boil!). At this stage you can change the consistency by adding more water (or flour to thicken). I added more water as it seemed to be quite thick!
