Why is my gouache paint cracking?
If insufficient water is used to dilute the colour, the thicker film may crack as the paint dries on the paper (note that the amount of water needed will differ with each colour). If you are painting in layers, the later ones may show cracking if the under layer absorbs binder from the wet colour.
