This model can be folded from practically any kind of paper. A 20 cm square of copy paper is a good start, but you can fold this model even from a sheet as small as 8 cm.

1. Start with a square sheet, white side up if folding from duo paper.

2. Fold in half.

3. Fold corner to the vertical helper crease.

4. Unfold.

5. Valley-fold along the diagonal, but only between the corner and previously folded crease.

6. Grab the corner by folding along the creased segment of the diagonal.

7. Collapse, flattening the model. The edge of the paper at the bottom should form a straight line.

8. Unfold everything.

9. Fold a segment of diagonal in lower-right corner, only until it meets the first crease.

10. Start collapsing as in step 6.

11. Grab the lower-right corner while creasing the diagonal segment. You should be able to move the corner around.

12. Align the corner so that the folded edges of the paper on the right form a single straight line.

13. Rotate the model and fold up the almost triangular flap of the paper at its bottom.

14. Pull out some paper and flatten in order to get a sharp corner.

15. Pivot the sharp corner and flatten. A good reference point is when the crease visible on the model meets the base of the previous spike.

16. Mountain-fold the extra paper at the bottom in order to hide it.

17. Mountain-fold the corner at the bottom and rotate the model. The hedgehog is now ready.
