Time: (I haven’t made one with Joeys yet!)
Equipment: Printed parts (download from here, select one for your location. Another option is here. If you are in Perth, and would like a very simplified version of the wheel [nine constellations seen from here], comment on this post.)
AoPG: Intellectual, Character
Copy or print the Planisphere parts onto paper or light card. Cut out the Pocket carefully, including the window. Fold the tabs on the pocket carefully.
Insert another sheet of paper (or light card), and tape the tabs down.
Cut out Wheel carefully. Insert into pocket and cut the pocket to shape. Decorate the pocket if desired (careful to avoid the functional parts!)
