I Love this great idea on how to create your own home made bath paints! My girls love painting in the bath and shop bought paints are expensive and not always what they are cracked up to be! We have tried quite a few bought paints and have found some are not very colourful and others get dropped in the bath and dissolve quicker than you can say 'paint'!
Why not try using this recipe to concoct your own = 1tbsp cornstarch, 4-6 pumps baby shampoo, 2-3 drops of food colouring, 1tsp of water. Good Luck!
