Coffee!

When C told us that she did a "coffee" painting, we thought she drew a still picture of a tea set and then she recounted that there was a mermaid too.

I conveniently assumed that it was a mermaid having a tea party or something and then she came back with this...

The painting has a lovely brown stained effect and the aromatic smells of coffee filled the car. 

Then we realised that it was real coffee that she had used as paint. Nice!
