- This is a new title in the delightful extension of the best-selling That"s Not My... series which gives children the opportunity to colour in the well-known illustrations of Rachel Wells. With a coloured-in picture to act as a guide, and a black and white outline to colour on the opposite page, children can follow the colours as closely (or as loosely!) as they like. Children can complete the simple phrase That"s my - at the bottom of the colour-in page as an aid to learning their first letters. Colourful stickers encourage creativity.
