After experimenting with paper, shells and shoes, Instructables user JyotiYadav was on the look out for something new to marble. "Then I had the 'Eureka' moment. Marbling on umbrellas. It was the perfect surface for doing marbling as the flat surface of the umbrella wouldn't distort the design."
The process involves filling a basin with water and sprinkling paint on top to create the swirls. To stop the umbrella tilting to one side when you push it into the colourful water, JyotiYadav made a metal frame to distribute the force evenly across the surface.
