Carla Sonheim posted a tutorial on her BLOG on how to marble on water with fingernail polish. Here’s the link http://www.carlasonheim.com/marbling-with-nail-polish/. She makes it look so easy! I didn’t have such great luck. The polish dried on the water pretty much immediately and I was unable to get it to swirl around much. And, once it dried, the polish is flaking off the paper. I’m sure I’m doing something wrong.
