This bird started out as a swan, enjoyed a brief stint as an ostrich, and ultimately--quite unexpectedly--became a road runner. The technique is flat needle-felting. It's usually done with wool rovings on a wool ground. But I ran out of rovings, and I wasn't finished, so I added some wool yarn scraps that I had leftover from a knitting project. This turned out to be a good move, since I think the yarns give it a lot more interest.
One hour into the project, I was hating needle-felting, but two hours later I wasn't hating it quite as much. Pushing through the resistance to an unfamiliar process can be a worthy experience, and it can yield some interesting results.
