Wonderful challenge over at Mixed Media World, Under the Sea.
This is what I have come up with..
On a reclaimed piece of wood, I squirted out some Pebeo Dyna paint in Blu Black and Blue Green. With a painting knife, I moved it over he wood and mixed up the colours. The propeller is from a magazine, so I fussy cut this out and placed over the wet paint.
The next day when all was dry, I drew the fish with a white Sharpie pen in a Zentangle style. I added some Dyna Iridescent paint in Red Blue to add some details to my fish. The eye is a die cut.
Another view to try and capture the iridescence!!!
