A few weeks ago I had a project: to create a rabbit hand puppet. Above was the first attempt. It looks vaguely rabbit-shaped, although the ears are a little weirdly placed. You may notice that this isn't exactly a puppet, more a stuffed rabbit softie. Well, partway through the sewing, I realized that my plan for the arms would make it such that the wearer would not be able to put fingers into the arms. So I just sewed it up and made a doll out of it. Here's the cutie backside, with a puff of faux mohair for the tail:
The next version. A disaster. The resemblance to a rabbit is diminishing. Granted, you can now put fingers in the arms. This version was abandoned.
And the final version. More bunny-like, fingers can work the arms. I still need to add facial features, but this is much better than the beginning attempt.
