I want to keep the random splatter of paints my baby made when playing with paints for the first time.
The problem is that the paints are edible paints I made using corn-starch, water and food colouring. I assume these will go off / go mouldy over time.
Is there anyway to preserve this? Would Lamination work? Is there anything less plasticky looking I could do such as spraying the paper with something?
