I once saw a girl with a bag sewn to look like a sweatshirt. I studied it and decided to make my own bag out of a sweatshirt. It turned out looking pretty different but its still cool. I sewed up the bottom and sewed the sleeves together. I also put a slit at the neckline to make it easier to open and get into. I let the hood fall over for the flap. It works great and I can put a lot of stuff inside it.
