Hi Sue,
Batik technique is pretty simple. Emboss your image (bold is better) and white mulberry paper in white. Next add different color re-inker onto your mulberry paper with a watercolor brush or just wet the paper a bit and then drip the re-inker on there.
Check out this sample in the gallery:

There are instructions there from the stamper as well.
Hugs and smiles.
