Eric Joisel - Baby Hedgehog

Baby Hedgehog © Eric Joisel http://www.ericjoisel.com 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. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16.

Fold the square 16 x 16 units horizontally and vertically; Mountain-fold diagonally the 30 indicated creases; Valley-fold the other diagonal 32 indicate creases; Make these 4 pleats:. The mountains already exist, the valley-folds need to be created; Make these 3 mountain-folds. The dark-grey squares figure the 5 ranks of shapes; Turn into “REAL 3D”. This step shows how to make the first 3 central shapes; See the result in the photo. Continue similar process to make the whole central shapes pleat; The central rank of shapes completed; The 3 first shapes of the 2nd rank. This step is especially difficult to understand and produce; 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; The 5 ranks of shapes completed. Next step would be seen from the left; Form the 4 legs (“pure box-pleating” technique...); Legs completed. Next step would be seen from the right; 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); Result. Unfold 2 shapes to form the tail, 4 in the opposite corner to form the head; 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
