So this is Doris, or 'hedgehog mark 3', as I like to call her. I have made a few changes. The muzzle is slightly longer; the legs are slightly shorter; I have added some black paint to her face; and I haven't felted the legs.
I'm not too sure about the legs. They are thread-wrapped - which is what I did with the other two hogs, except that there, it was only a sort of intermediate process of covering the wire and providing something to felt onto. Since the felting was making their legs look quite, shall we say 'sturdy'(!), I thought I ought to try missing out the final felting stage. This meant that the thread-wrapping had to be glued though. I added enough wool thread until the legs looked the right shape, then sprayed them with adhesive glue (a mistake, I think - it went absolutely everywhere), then a thin layer of thread over the top. It feels fairly firm, so I'm hoping it will stay put.
I'm really happy with Doris; I do think she looks quite realistic. However, here is still something not quite right about the proportions. I think hedgehogs have longer muzzles still, but perhaps slightly deeper as well? Her head looks slightly too small in relation to her body. Next time I'll try to rectify this.
