The blue tray you see needs to be half filled up with cold water.
You add the paint thinner to the oil paint and stir it well. Then pour a little into the tray of water. Next, lay your sturdy drawing paper on top of the water. Pick your paper up by the corners, and lay on newspapers to dry.
This is my paper that I marbled. Water and oil doesn't mix,so the oil paint floats and swirls in the water.
This is when I was done marbling paper with my brothers.
