Mastering cold wax medium techniques requires creativity and practice. Begin by mixing cold wax with oil paints for rich textures and faster drying times. Use palette knives, brayers, or squeegees to layer and scrape back the wax, creating depth and dynamic surfaces. Work on absorbent surfaces like wood panels or heavyweight paper for best adhesion. Build layers gradually, allowing each to set slightly before adding more. Enhance details with mark-making tools like combs or sticks.
