Meet the cast — the characters who teach this
-
Hingely (Hero and guide, a paper-crane engineer) - everything turns about the spine, the fold in the middle of the card -
Flatsy A flat-folding lizard - a pop-up folds flat when it is a parallelogram: opposite sides equal -
Pokey A curious heron - closed, the fold sits depth plus height from the spine, so too big pokes out -
Gluey A beaver with glue - the panels must add up to the distance they lie along, or the paper tears or bows
