All you need for finger painting is a bowl of water, water colours, paper and a pen.

Draw some shapes or objects on the piece of paper: a tree, flower, butterfly, hill, sun, etc., with out to much detail. Talk to the child about the picture: what is this, where is the flower...

Show your child how to colour one object in the picture using the tips of its fingers, water and colours, and making dots one beside the other within the surface area of the image: tree, flower, etc.

Colour object by object, and use one colour at a time.
