Assorted colors of oil paints or marbling inks (the inks work better)
Plain, white paper (computer paper works best)
Oven pan covered with aluminum foil (make sure the pan is big enough to fit your paper)
Water to fill pan
1 teaspoon vinegar (if using marbling inks)
Newspaper to cover your work area
Pencil or toothpick
Fill the oven pan (with the aluminum foil over it) with water.
If you are using marbling inks, put the teaspoon of vinegar in the oven pan, and mix well.
Put in just a tad of the marbling inks or oil paints (using two or more colors works best). Swirl the colors with the pencil or toothpick.
Put the paper in the pan slowly. Work quickly, especially when using oil paints. If you do not, the paint will make a sheet on top of the water, and you will not be able to marble.
Take the paper out and put it face down on the newspaper for about a minute.
Use the paper when completely dry.
