Drawing inspiration from the title "Allez", all three of my covers were designed to create the sense of finding a hidden gem of a building in a foreign city. Learning a different language may be daunting for some children so by using soft colours, familiar types of buildings and white type, a non-intimidating tone is produced.
As you progress through the books the names of the buildings become slightly less familiar, from the well known Cafe, to a Boutique then to a Livres (bookshop).
Familiar elements are present in all books so you can tell they are apart of a set. Colours change slightly to show progression in learning.
