This model is in “real 3D”, so itʼs considered as “complex” during origami conventions... 3 hours minimum and a strong paper is required to fold it. A good size for your first attempt would be 20 cm square (8 in square).

1. Fold the square 16 x 16 units horizontally and vertically;2. Mountain-fold diagonally the 30 indicated creases; 3. Valley-fold the other diagonal 32 indicate creases; 4. Make these 4 pleats:. The mountains already exist, the valley-folds need to be

created;5. Make these 3 mountain-folds. The dark-grey squares figure the 5 ranks of

shapes;6. Turn into “REAL 3D”. This step shows how to make the first 3 central shapes;7. See the result in the photo. Continue similar process to make the whole central

shapes pleat;8. The central rank of shapes completed;9. The 3 first shapes of the 2nd rank. This step is especially difficult to understand

and produce;10. The 2 first ranks completed. You can flatten the different creases ONLY when

every rank is finished. Next step would be seen from the right;11. The 5 ranks of shapes completed. Next step would be seen from the left;12. Form the 4 legs (“pure box-pleating” technique...);13. Legs completed. Next step would be seen from the right;14. Carefully stretch every shape into the arrows configuration, so that the 5 ranks

would form a curve. (in small sizes, small tweezers can replace your fingers);15. Result. Unfold 2 shapes to form the tail, 4 in the opposite corner to form the

head; 16. Your model could look like that (but other type of heads are possible).

Finish the model by wet-folding.

This is for the BABY hedgehog (5 ranks of shapes). “Mother” and “children” are produced from a 32 x 32 grid (step 1), producing a 3D form with 9 ranks of shapes instead of 5. The folding is quite similar for both models. HAPPY FOLDING
