Mix this easy to use powder with water and soak fabric or other surfaces in the solution to prep them for water marbling. This helps our Water Marbling Acrylics stick to surfaces, allowing for better transference. Use this to prep surfaces like silk scarves, canvas, fabric shoes, and more! When water marbling, no two designs will be alike, the surprise and unique quality of each design is part of the magic and mystique of this ancient art form.
