The document discusses primary and secondary sources, formal elements, materials and techniques used in The Equivalents Project. Primary sources are original works directly observed, while secondary sources refer to existing works by other artists. Formal elements like tone, composition and texture were important to consider when creating still life drawings and sculptures. A variety of materials were used including ink, charcoal, cardboard and paint to create textures and tones. Safety precautions must be followed when using equipment and materials in the workshop.
