Marbles <RELIABLE>

Creating marbled paper involves preparing paper with an alum mordant, creating a thickened liquid "size" base using carrageenan or methyl cellulose, and floating acrylic paints on the surface to create patterns. The design is transferred by placing the treated paper onto the surface, lifting, rinsing, and drying, with options for traditional, acrylic, or kid-friendly shaving cream methods.
