I've only just begun

Yes, admittedly I've only just begun, but I have been sewing today. And about time too, before I forget how it is done! I'm making box bags following this tutorial. Mine will be quilted, though. I spent some time wondering how to go about it, adding zippers and all. Eventually I decided to quilt the outer layer with batting and a cheater fabric that will be hidden inside the lining, and just follow the tutorial from there on. And why make one, if you can make four?
