I have to mention the tutorial I found and used for closing the seam. It was just what I needed and it worked great! I was amazed. Go to Quilt Taffy to see how to finish off a stuffed animal with an invisible closing seam!
I don't know how I'm going to hold off another week before giving this to my baby. I showed her brother and he said, "Wow! Can I see my stuffed Batman"? Mind you, there is no stuffed Batman but apparently there's gonna have to be now! I will be sharing that tutorial as well as their coordinating twin quilts (since they share a room) in the near future.
