The spines of hedgehogs and porcupines are known as 'quills', and the photo on this card shows a lovely little hedgehog who regularly visits our garden. He let me get right up close to take this picture:
Of course, I then couldn't resist trying to quill a hedgehog as well! I made this one by making a D-shaped coil with a brown strip, and then attaching some fringed sections which I had coloured in roughly using a brown marker pen. The hedgehog's real quills are brown and beige, so I used a beige fringed strip to colour, giving a mottled effect. Then I just added a little rolled black nose!
