Charley Harper - The American modernist artist and illustrator has produced some beautiful books based on nature and in particular, birds. The Deluxe Colouring book looks so classic and simple.
Rosie Flo's. - Lovely drawings that require children to use their imagination and draw in body parts to the outlined dresses or figures, in all kinds of situations involving music, gardens, kitchen, games etc. There are 8 books for girls and 2 for boys (action-led figures). There are also a couple of posters to colour as well.
Looks like another Amazon order might be on the cards!
