So we took some old socks, turned them inside out and cut in the middle of the toe for the ears. I used a sewing machine to sew the ears, much faster. I then stuffed the bunnies and closed the bottom with a hand stitch. You can play with this to get it how you want. Then the eyes either just buttons or a circle of felt under the button and sew both on at once. Then mouth and nose and voila..you are finished!
