I made one without a pattern, just undid the side seams & covered the whole thing with raw edge squares & FMQ the whole thing, then removed the ribbing & added a collar and zipper. Also made another from a pattern, will have to check if I still have the info, you undid the side seams & sewed strips to the body part but left the arms the sweatshirt fabric (poor description) will try to get info later today.
