Andamooka is on the edge of the ancient Eromanga Sea. Andamooka is famous for precious opal, formed in the fossilised bones of Cretaceous marine creatures.

But that's another story.

This story is about Mary, who asked her friend, Heather, to teach her how to mosaic.

Heather wasn't keen. She didn't want to be a mosaic artist anymore.

Heather was sure she'd given up mosaics. She felt weary after completing her ten-year plan to mosaic the external walls of her house in Nuriootpa. Heather's new plan was to spend the winters in the arid zone, learning about fossils and fauna and flora.

Mary was quite convincing. Maybe Heather wasn't ready to give up mosaic.

This is the true story about two friends creating a mosaic mural and the people who helped out along the way, especially Chado.

This is a digital version of the original concertina collage composition created by Heather for Mary's daughter, Rosalyna.

Heather is an artist, author and children's book creator. She enjoys having adventures and learning about fossils.

Another of Heather's mosaic stories is Barossa Nanna and the Counting Book - Bushland Mosaic.

Look for "Andamooka Trish and the Broken Dish", an instructional text about how to use crockery to create mosaic.

Heather's mosaics and collage can be viewed on social media at "Rhagodia Mosaics and Collage".
