It is hard to find nice bunny patterns! I have to make one this fall for a friend and have been looking. There was a cute pattern that sold on ebay called Hare Raising Experience by Prairie Grove Peddler - ©2003. It is a few bunny heads amongst leaves.
I would like to use minky type fabric for their bodies so that they are more tactile and feel soft. Last year I made one with sheep - the bodies were made with white cabbage rose minky and their faces and ears were flannel. There were 5 in separate cotton blocks that looked like fencing - turned out really nice.
