I always try to crochet a blanket for any new babies in our family, and my niece had her 2nd baby girl recently, so I made a blanket for the new baby, and a stuffed bunny for the "big-sis".
I found the bunny pattern on the Lion brand yarn website. It was one of the most challenging projects I've completed, not because the crochet stitches were at all difficult, but stuffing the tiniest parts (The bunny is only about 6 inches high) while finishing crocheting them, and sewing it all together was not like anything I'd ever done before. I don't know if I'll make another bunny, but I'm told my niece was thrilled with it, so it was definately worth the effort.
