We found a 3 ingredient puffy paint recipe that is easy to make and and you use your microwave.
To make your own homemade puffy paint, you’ll need:
1 tbsp self-rising flour
food colouring in the colours of your choice (I used Wilton icing gels) see below
1 tbsp salt
little bit of water (start with 1/4 tsp)
