I was making this for my sister. The directions said just use a sweatshirt. The only place I could find one was at Walmart. As I was nearing the end, it occurred to me that this jacket was going to be short. Even though she is petite. Should I sew a band around the bottom out of the brown like the sleeves. I'm so disappointed. Lots of work not to mention the cost and I wouldn't blame her if she never wore it like it is. Appreciate any help.
