My wife made this for our son last Halloween when he was just under two years old. We wanted something that would be easy to make, keep him warm and be easy for him to wear around. Our only goof up was that we made the stripe wrong- and sewed the tail on upside down! Of course I fixed that for the instructions. :)
Step 1: Materials
You'll need a black hooded sweatshirt (preferably with a zipper- makes it easier) and pants, some white fabric, some polyfill for the tail and some velcro. You'll also need some matching black fabric to make the tail.
