How to use

Choose a comfortable, well-lit workspace and select a page from the boxed colouring book. Identify the numbered areas and the corresponding paint, crayon or pencil colours you plan to use. Colour each numbered section according to the referenced colour, working from larger areas to finer details to avoid smudging. Allow finished pages to dry if wet media are used, and store completed or unused pages back in the box to keep them flat and protected.

Usage recommendations

Use washable, child-safe colouring tools suitable for paper to minimise staining and ensure easy cleanup. Supervise younger children to select appropriate media and to avoid swallowing small items. For classroom use, provide clipboards or hard surfaces so pages remain steady while children colour.
