I would strongly advise to buy a full kit that comes with everything you need to start body marbling.
Marbling kit instructions.
The ancient art of paper marbling has historically been associated with the book arts.
Marbling is the process of floating fabric paints on the surface of a thick cellulose solution called size somewhat like oil on water.
Pretreat fabric or paper with mordant.
Then you capture your design by laying a treated piece of fabric or paper down on top of the paint to transfer the swirls to the fabric.
The floating paints are swirled into patterns.
These marbling kits are made for decorating objects and not people and can even be hazardous.
Soak leather or prewashed fabric in mixture for 20 minutes or brush onto paper.
A mordant must be used on paper and fabric so that the marbled design will adhere to the fiber or paper quickly and permanently.
Using the correct acrylic body marbling paint is extremely important.
Mix 3 tablespoons alum per quart of hot tap water in a bin.
