I’ve been working on a dinosaur tail and a pattern to make one for a while now, it’s been quite a challenge but I finally got the pattern finished and tested a few days ago.  

Pattern is available over on my Etsy and Ravelry shop:

I opted for a green and beige mix, but you could use whatever wool colour combinations you like for this, you can also pick as many spikes you prefer so could opt to put more/less on than I have or use a different variety of the spike sizes available in the pattern.
