a while ago I remember seeing a book with instructions for making a variety of Lego models - think it may even have come with various bits of Lego eg wheels/gears etc. Fairly sure I saw it in one of the catalogues or on a website but sadly cannot remember which. Am I going bonkers or does anyone know what I'm on about or where I can find it (should it really exist and not just in my imagination!)
All help gratefully received as my son is Lego mad and keeps pestering me to help him 'design' planes/trains etc!
