Mixed media painting combines multiple materials like acrylics, watercolors, inks, and collage elements to create layered, textured works. To master this technique, begin with a solid base—acrylics are ideal as they dry quickly and provide a strong foundation. Incorporate textures like fabric, paper, or sand for depth. Use gel mediums to adhere objects and create 3D effects. Be mindful of drying times and compatibility between materials to avoid peeling or cracking. Keep experimenting to develop your unique style and expression.
