I found a pattern on Etsy and scaled it down so that it was half the size.
I used felt for the main structure and then covered it in purple minky, which is so amazingly soft, making sure the grain was the right direction to stroke. I was a little worried about sewing with Minky, apparently it's stretchy and awkward but with hand sewing, I didn't really find that.
The main is made out of faux fur and has some wire in to keep it taught and the eyes are made from felt. I tried to glue them on but had to sew them on in the end.
I haven't given it a tattoo or 'cutie mark' as I had originally planned to make this with the embroidery section of my now broken sewing machine (do not buy from Sewing Machines Direct or Cooper Sewing Machines). It's a little small to make out of felt but it would have had a see saw on one side and the sum of the moments equation on the other.
