This is a quick and easy idea to replicate how batik art works, without all the necessary expense of materials.
How about looking at some images of Batik art on Google images?
Then have a go of sketching a simple design on some paper.
Once you have chosen a design its time to try it out.
Using pva runny glue (try to find a glue bottle with a good nozzle first of all). Draw the image you want onto some dry water colour paper.
Let this dry for around 24 hours, or at least till its hard.
Gently wet the water colour paper and add the watercolours you want. You could leave salt on the water colour paint to give a special effect.
How about turning your masterpiece into a card and give to someone special.
