Developed by the Oswaal Editorial Board, Volume 2 of the Crayon Colouring Series provides a structured progression for children in the critical 2–5 age bracket. This resource emphasizes Visual-Motor Integration by providing simplified, high-contrast targets that facilitate focused attention. The deliberate use of thick-outline topography assists in the refinement of distal muscle control, essential for pre-writing development. With single-sided, heavyweight paper for optimal sensory engagement, Vol. 2 serves as an essential developmental bridge in early childhood art education.
