I have been making paper toys of every variety with my four year old since he was about two and a half. Most of them have been far too complicated for him to do alone, and frustrating for the adult who is helping along. Not only is Delphine's book gorgeously illustrated, inventive, and unique, it is surprisingly doable for a four year old with just a bit of help. The instructions are so helpful, and the addition of the heavy stock street makes this more than just toys to sit on a windowsill. They become, as the title says, My Town.
